The LEGO Movie 6: Return To Townsville

The LEGO Movie 6: Return To Townsville is a 2034 American-Philippine-Danish-Australian 3D computer-animated musical crossover comedy film produced by the Warner Animation Group. It is the direct sequel to The LEGO Movie 5: Top Secret (2029). It is the first crossover film in the franchise, and takes place one year after the events of the Netflix animated film "How Cartoonsville Was Created" by Guillermo del Toro. It is released on February 10, 2034 in 2D, 3D, RealD 3D, Dolby Cinema/Vision/Atmos/3D, and IMAX 3D by Warner Bros.

It's also the first film to be produced by Boomerang (new independent film studio of Cartoon Network and Warner Bros. Pictures) after the closure of Picturehouse Films in 2015, since The LEGO Unikitty Movie (released on January 2020 before The Loud House Movie), The LEGO Avengers Movie (also released in 2020 by Marvel), and The LEGO Movie 3: A PowerPuff Adventure (released in 2023 theatrically; 2024 on Boomerang UK and Asia on April 2) were the franchise's soft reboots.

Synopsis
The citizens of Syspocalypstar have been going on their newest tradition of all— music. After learning about how Cartoonsville, another glorious city with a castle, was created, Emmet, Wyldstyle, Batman, Robin, Batgirl, Blossom, Bubbles, Buttercup, Unikitty, Puppycorn, Hawkodile, Dr Fox, Ricky, Sweet Mayhem, Queen Watevra Wa‘Nabi and the rest of the Master Builders are on a trip from Syspocalypstar to the Kingdom of Cartoonsville, after learning information about the fourth PowerPuff Girl, and the rest of the city. The PowerPuff Girls reunite with Bliss, a rightful ruler and queen of Townsville. Eventually, Batman and Wa’Nabi are looking forward to adopting the Loud kids. When a dastardly plot of the Big Boss, a leader of sinister Playmobil loggers, arrives, Emmet must join forces with his friends and the other Master Builders (both LEGO and not LEGO) to fight back.

Plot
Six months after the events of the previous film, Emmet and his friends are celebrating the new year in the town of Syspocalypstar. Emmet and Lucy ask Metal Beard and Benny where their kids are, but Benny tells them that he left them with Feebee. Just as the PowerPuff Girls are about to light the fireworks. They talk about pirate techniques and how they stick together, then they light the fireworks. They run to the Statue of Liberty, and watch as the fireworks go on.

One year after the events of "How Cartoonsville Was Created", Blisstina Francesa Francia Mariam Alicia talks with Spider Ham at Emoji-San about uniting the worlds. Spider Ham tells her that the universe on sending that message is pending. Bliss appreciates the idea about the message. They go outside, and tell Cartoonsville's citizens about how they built this place and how her predecessor became the Spirit of Cartoonsville. They both agree that the universe will send a message to Syspocalypstar.

Meanwhile, Emmet gets some coffee, greets his neighbors, greets Iron Man, and heads home for some breakfast. Wyldstyle is cooking pancakes. When Emmet headed home, he serves the coffee and hot coco to the family. Hawkodile finds some files about the late Kingpin invasion that ended during the ending of "How Cartoonsville Was Created". Everyone agrees. Meanwhile, the Playmobil leader, the Big Boss, had to get his boat ready to get revenge on Bliss.

Emmet drives to Queen Watevra Wa'Nabi's castle, and finds them preparing for the auditions. Emmet tells them that they are going to Cartoonsville. At the Avengers tower, he meets up with the Iron Man, Hulk, Spider Man, Nick Fury, and among others, including the Guardians of the Galaxy. Nick Fury tells him that he should participate in the family trip. Back at home, the Brickowski family pack up, as the Justice League and Avengers arrive. At the seaport, they enter a ship called "The BatBoat", which is loaded with Duplo aliens, hearts, stars, and their accessories.

When the Big Boss arrived at the docks of Cartoonsville, he tells his henchmen that they must put an end to Cartoonsville and demolish the entire village if there are any signs of life. The rest of them are hired to cut down some trees.

The Master Builder's arrive at Ninjago City, and get the Secret Ninja Force (including Koko), Master Wu, and then Lord Garmadon. They arrive at the flood ruins of Townsville and get taken to the gates of the new society. They meet Bliss and Spider Ham. Bliss reunites with the PowerPuff Girls, and they open the gates. They tell them about how they built this place and why the Kingpin invasion stuck around the alternate universes outside of the LEGO Universe. The gang meet Beemo, and then a pink 1980s Classic Spacegirl named Penny. As the musicians start blowing on the didgeridoos, everyone sings and dances to the tune of "Beautiful Creatures".

Back at Emoji-San, Hi-5 is looking forward for the Loud kids to get adopted. Gene then meets up with Jailbreak, and tells her that the Loud kids are gonna be adopted. Meanwhile at Red's hut, the Loud kids chat with Red, Chuck, and Bomb until Gene arrives and tells the Loud kids that they are adopted and he found a flyer for tomorrow's auditions for the Festival of the Triple Decker Couch. The Loud kids then cheer.

Meanwhile, the Systar gang had just recently finished putting up the flyers around the town to spread the word. And after the exploration of the entire kingdom, Benny and Penny meet up with Emmet and Lucy. Penny tells them that they are staying in the castle, because it was sundown. There they meet the Loud kids. Buttercup tells her adoptive dad that the castle has 12 bedrooms. Penny then flies to her bedroom, and everyone goes to sleep.

The next morning, Buttercup and the Loud kids wake Emmet up with a spider. Then they run out as Emmet gets the spider off of his body. He sees Red, Chuck, and Bomb, and he tells them that on days in the kingdom, they start early. Chuck tells him that the queen will meet him at the forest. Emmet then leaves for modern training, and Lucy, Bubbles, and Buttercup leave for work at the sorting area.

Meanwhile at the Cartoonsville Stage Theatre, Blossom, Pepper Potts, the Bat Family, Iron Man, the Secret Ninja Force, and Unikitty and her friends notice that there are a bunch of people waiting in line for auditions. After auditions, Dr. Fox selects the following: the Loud kids, Joker, Harley Quinn, Grizz, Panda, Ice Bear, Kevin, Stuart, Bob, the Wattersons, the UglyDolls, the LEGO Friends characters, Iron Patriot, Starfire, Raven, Beast Boy, and War Machine. Each UglyDoll has a different pair: Moxy is paired with Ox, Wage is paired with Babo, and Ugly Dog is paired with Lucky Bat.

Meanwhile at the forest, Bliss teaches Emmet the basics of Cartoonsville protection mode because it was training day. She teaches him the following: covering in mud, push-ups, camouflages, plucking and apple from a tree, and cutting a rope tied on a person. After flight training, Bliss shows Emmet the apple trees that feed and sustain the citizens of Cartoonsville. Veronica and her crew arrive to confront Bliss. She tells Emmet that Veronica has her own side of the kingdom which is anime, because food was really scarce. After sightseeing on loggers, Emmet confesses to Bliss that Syspocalypstar was a mishmash of Apocalypseburg and the Systar System. Bliss tells Emmet that he needs to unite their worlds in peace again, this time with the many realms in the LEGO universe. Emmet agrees.

Bliss and Emmet meet up with Lucy at the sorting area run by Dipper Pines, their foreman. He tells the workers to get the bricks from the Bin of Storajj sorted and up to Emoji-San before the party starts tonight. Bliss tells Lucy that Emmet's training was educational. Penny introduces Emmet to her friends Helda, Holly, Kate, Anne, Hanna, and Darla. Helda is daring and does brave stunts. Holly is shy, but caring to animals and other people. Kate is the toughest space girl in the group. Anne is the comedic girl of the group, Hanna is the shopaholic in the group, and Darla is the playful girl. After a protection mode, Emmet starts washing up as he runs off.

Back at the theatre, Dr. Fox tells the performers that they were her chosen many, although she had to dismiss Twilight Sparkle and her friends. In the corner office, Dr. Fox talks with Unikitty about how they had an idea for the show on the Festival of the Triple Decker Couch. Then she is visited by Gene, who appreciates the Master Builder show. Dr. Fox dismisses the performers for tomorrow's rehearsals. The performers get on the party bus.

That night, when the gang got to the party, they meet the warriors of Cartoonsville. Bliss reveals herself as the leader of the clan and also the queen. After a few minutes of dancing and wining and dining, the queen steps up for a speech. She tells the party members about the Kingpin invasion and how their home was created.

After the party, a few minutes later, everyone goes home. The next morning, the performers arrive at the theatre just in time for rehearsals hosted by the Systar Gang, the Secret Ninja Force, The Unikingdom gang, Tony Stark, Pepper Potts, and the Bat family. Wa’Nabi gives them the list of songs she had listed down, only to notice that the Mane 6 just barged in one of the rehearsal spaces, so she had to tell them no. Dr. Fox shows the Loud kids about how they merged the worlds during the Kingpin invasion that happened in the parallel universe, adjunct from the Duplo invasion from the LEGO Universe, as she turns on the house lights. She tells them about how the Duplo aliens invaded Bricksburg, how Apocalypseburg was built, the matrimonial ceremony, the brink of Armamageddon, the song “Everything’s Not Awesome”, the birth of Syspocalypstar, the Bin of Storajj, and catchy pop music. She then guides the kids to the rehearsal spaces as she runs upstairs to the corner office.

That afternoon at the castle, Emmet packs his stuff in his bag. When he notices a photo of the destroyed city Bricksburg, one of the photos of the LEGO Universe kept on frames, he gets flashbacks from Apocalypseburg, until Lucy comes in and tells Emmet that she has the Hulk trio from the sorting area. The first one is the Hulk big fig, the second is the Hulk minifigure, and the third is a Hulk Duplo figure. They found out that a new foe called the Big Boss is coming. But Emmet says that he is so far away from the village.

That night, Emmet visits Finn and Jake in their treehouse. Finn tells them that they have a life coach named Donny, who is a unicorn. Jake tells them that he got them on a schedule: Mondays: take out the recycling, Tuesdays: mow the lawn, Wednesdays: go visit Oh My Disney Con, Thursdays: pick some apples. Finn then shows Emmet the image of Oh My Disney, which was seen on “Ralph Breaks The Internet”. Emmet says that Unikitty is a princess, so she must have a song when she stares at important water.

The next day, Ugly Dog performs by dancing to the tune of Eiffel 65’s “Blue (Da Ba Dee)”. When Batman accidentally launches a Baterang at the switch of hanging lights, they fall down behind, scaring Ugly Dog, only for him to blame Luna Loud for almost killing him. Then the lights start to burn. No one gets hurt though. Unikitty gets a fire extinguisher and puts the fire out. Even after the accident, the group gain two more acts: Skipper, Kowalski, Rico, and Private, as well as the Mane 6. When Luna Loud follows the steps while singing “Play It Loud”, a minion shows up and messes up the papers. Queen Watevra Wa’Nabi showed Leni a song that she will sing tomorrow. Hawkodile shows Nicole a song entitled “After A While Crocodile” for tomorrow’s auditions.

In Emmet’s dream, Lucy is happy and has recently arrived at the tree forest. Emmet shows up and picks an apple for her. At the end of his dream, he prepares to do the “breakfast in bed” job as he drives off.

The next day, The Joker drives his car faster, causing two cars to collide. Leni is called by Dr. Fox to sing “Call Me Maybe” but she ends up breaking down in front of Dr. Fox and Hawkodile. Panda and Luan called in to perform to dance to “Ninja Re Bang Bang”, as Unikitty is called by Finn and Jake to be at Oh My Disney, and when she arrived, she asks some members of the con where the Princesses are, but later gets chased by some Stormtroopers and bumps into some 20th Century Fox/Blue Sky Studios characters. She then jumps into the door of the Disney Princesses, and the Stormtroopers lose her. Meanwhile, Emmet drives his car faster to get to the apple tree forest, but ends up in a traffic jam. Back at Oh My Disney, Unikitty meets and befriends the Disney Princesses, being encouraged by them to address her sense of unfulfillment and reaching a musical epiphany as Unikitty asks them to sponsor the Festival. Meanwhile, when Emmet tries to pick an apple for Lucy, he accidentally tries to get it in the territory of the Sinister Spacegirls, led by the hostile Veronica. Emmet inadvertently causes war between the two borders for food when he accidentally hits Veronica with a twig. The war turns out to be just like football (soccer), and Emmet accidentally costs the kingdom the food when he scores an own goal.

Emmet apologizes to Penny for his mistakes. After accepting his apology, Penny notices that the loggers are near. She knew one thing that she needed to do.

At the theater, Penny and Emmet interrupt the rehearsals, and tell the team that the loggers are coming, and they told the same to the queen. Before evacuating, the citizens of Syspocalypstar show up and stop the citizens. The other citizens of Gotham City, Ninjago City, New York City, the Old West, Heartlake City, Unikingdom, Wakanda, Asgard, Bikini Bottom, Maranello, Bird Island, Piggy Island, Eagle Island, and Middle Zealand also show up, along with the Gotham City criminals. Emmet reveals that the Duplo aliens are their secret weapons for backup. Emmet persuades the citizens to defend their homes, and they easily outmatch the loggers with help from Veronica and her crew and the other Master Builders. The Big Boss tries to blow up the trees as a back-up plan, but Emmet steals the lit dynamite, using his Iron Man Mark 7 suit. He flies up, then throws it in the air, and the dynamite goes off, causing Emmet to fall. Luckily, the Disney Princesses save him from falling to his death. Victory was theirs. Meanwhile, the Big Boss is eaten by a boa constrictor he encountered.

Afterwards, everyone including Bliss hail Emmet and Lucy the new heroes, and the citizens of Syspocalypstar, Cartoonsville, the Old West, Middle Zealand, Heartlake City, New York City, Gotham City, Unikingdom, Wakanda, Asgard, Bikini Bottom, Maranello, Bird Island, Piggy Island, Eagle Island, and Ninjago City make peace, and merge their hometowns to create the new city of New Bricksburg, which is peaceful. Garmadon has hired one of his new generals to fuel his volcano with more lava if the lava runs out. The Loud kids rebuild the Loud House a home of their own, and Emmet and Lucy still settle in their house, and their friends, including the Justice League, the Secret Ninja Force, and the Gotham City Criminals, are now neighbors as Unikitty gets back her castle. Batman and Wa’Nabi now settle in Wayne Manor. The Statue of Liberty has risen up again from the pit of fallen debris, and is taken back to its rightful place on Liberty Island. Much of the new city uses all elements from Radiator Springs and Propwash Junction. With the new city now under the protection of Emmet and Lucy, all the Master Builders celebrate their victory. Lex Luthor arrives in New Bricksburg, and the Phantom Zone monsters join the Master Builders' party, along with everyone from other countries and continents around the world, and the “UniKitty!” universe, among other countries and locations, including outer space, the moon, and skydiving. Emmet and Wyldstyle agree to live in New Bricksburg as the Master Builders party on.

In a mid-credits scene, set in the universe of the “UniKitty!” show, a hand drawn animated version of Dr. Fox talks to us about “Unikitty! The Movie”.

In a post-credits scene, we see a closeup of the Apple Tree Forest, now located in New Bricksburg. The boa constrictor has already eaten the Big Boss, and he pukes up the lollipop. Sheldon the Monkey grabs it, puts it in his mouth, and glares at us before running off.

"Hi, guys! It's Dr. Fox, and I'm here to tell you about our new feature film: Unikitty! The Movie! It's filled with wonder and magic, and is connected to the LEGO Universe. The movie producers are still thinking of its plot, but I hope you guys consider this the best hand drawn movie ever! See you this November!"
