Animated Movie??

okay everything I remember about this is very vague so I’m not confident BUT

it was an animated movie, and they lived in a nice world but either one of them fell over the edge or left on purpose and there was a really run down and crappy universe kind of below theirs? That’s basically all I remember

i thought of it when I was thinking about robots so I’m not sure if they have something to do with it

 

PLEASE HELP

Got something to say?
