Intern: I can't believe Nickelodeon was founded on this very day 45 years ago. Imagine how many actors, people, artists and especially characters for young and old have participated in this very long legacy.
Veteran animator: *sighs* Yeah. *The two stop and look at the studio, dreamily* If only these walls could talk.
*They leave, leaving the studio empty. As the camera turns towards the inside, the title of the short, "Once upon a Splat" appears on the screen, and it disappears as the camera focuses on a portrait depicting SpongeBob SquarePants, Sandy Cheeks and Mr. Krabs as they appeared in the SpongeBob SquarePants episode "Karate Choppers". Just then... the three suddenly start moving. *
SpongeBob: Psst! Nick! Hey, Nick! Are you there?
*Followed by a large amount of slime, Nick (from the original Nick Jr logo) pops out of the nose prop from "Double Dare"*
SpongeBob: *as he puts on his Krusty Krab hat* Is That? Are They all Gone? *Nick Gives him a thump's up and then... the yellow sponges leaps out of the picture* I'm Ready!
Sandy: *Jumps out of the picture beside him* Let's See if The Others Are! *Mr. Krabs jumps out of the picture while holding a cowbell with the number 45 on it* Mr. Krabs.

*Just as they're about to enter the studio through the gates, the characters all stop as they hear music. Mariachi Owls from "Rango". They're playing. "When you wish upon a star" on their instruments. Lori Loud from "The Loud House" follows playing her trumpet (from the Loud House episode "house music") and Sven hook from "the Ren and Stimpy Show" does the same on his accordion. While all this happens, a text that says "Since Nickelodeon doesn't have an emotional signature song, I had to with this one" appears on the bottom of the screen. *
