No,this isn't a parody of the banana splits movie. This movie is based on the slendytubbies 3 story,the 1st act of the movie is chapter 0 (yes,the game starts you off with chapter 0) it was good,which explains the origins behind tinky winky and on how the other teletubbies were killed and how he got infected. This scene was a sense layout of laa laa's death,hope you enjoy this quick teaser!
