The handprints could be literally anything at this point. It could be from Purple Guy lifting off the head, or it could be from a kid who jumped onto the stage. They might not even be handprints.

What I'm saying is, they may fit perfectly into one theory, but the evidence about Mangle far outweighs evidence for Freddy.
