37 Simba Farts - Kingdom Hearts
38 Kingdom Hearts: The Legend Goes On - Kingdom Hearts
Based on what many (including myself) consider to be one of the worst animated movies in history, Titanic: The Animated Movie. This awful KH spinoff will also feature cameos and appearances of characters and such from other bad animated movies (Disney and non-Disney), too.
39 Sora's Magic Voyage - Kingdom Hearts
Another KH spinoff, this time a crossover with The Magic Voyage, another god-awful animated film. In this horrible train-wreck of a spinoff, Sora will journey across the sea and will be accompanied by Pico the annoying and obnoxious woodworm as well as Timon and Pumbaa. Oh geez...
Sorry, I had to give myself a good laugh after writing these awful spinoff ideas of KH... You know this could actually work in fanfiction. Surprised that these ideas haven't been made, yet.
