the Ultimate Fiend: a Making Fiends Movie is an animated action/adventure horror comedy based off the show and web series of the same name.

It is also an adaptation of webisodes 18, 19, 20 and 21.

Plot/Summary
It takes Vendetta many attempts to destroy Charlotte so he makes one more effort to destroy her by creating a grand fiend (a combination of all the fiends and their ingredients, making it hard to make but possible to make by Vendetta) to destroy her once and for all.

With Charlotte preparing for moving day, Vinny, Render, Riley, Ramble, Thimble, Mack, Dee, Rex, Ramble, Malindia, Malachi, Marion, Maggie, Marvin, Sally, Manny, and the rest of the gang have some blue-related gifts for her to use as she begins her new adventures. Vendetta is then presented with a musical card by Charlotte. Outraged at this, Vendetta orders Grudge to get revenge against it by eating the card. However, the card continues to play throughout the day, and Vendetta kicks Grudge out of her house.

Rubella (Vendetta's Frankenstein-like replacement) arrives to Grudge's dismay, as she helps Vendetta make fiends with Vinny. She has a good time terrorizing the residents with them. At the same time, Charlotte records all the time she spent with Vendetta in Clamburg. In the process, Render and Mallard arranged for her to visit her new home.

Malindia receives a notification, telling her to meet Vendetta on the Clamburg docks. As Charlotte is heading to the docks (and singing "If A Dock Was Infinite" as she gets there), she puts Hammy and Joleene in charge. At the docks, she meets Vendetta and Rubella. More info TBA.
