I think the low detail of the background is very funny. Some of the tiles being colored for no reason, and having a blue outline when the rest is black to be pretty funny. The fact that Mangle isn't colored in, drawn badly, and colored red is funny. The jumpscare itself, is actually scary though. The Lunging face, being pretty derpy on its own, is funny, but it getting closer as if it's ATTACKING me makes me feel like it's gone haywire.
