In the movie Wreck-It Ralph, Sergeant Calhoun talked about her traumatic wedding day when a swarm of Cy-Bugs attacked her groom. Since we know that Cy-Bugs turn into what they eat and we know that Calhoun defeated the creatures, it stands to reason that at least one of the Cy-Bugs looked like her fiancé when she disposed of it.

Some fans out there seem to believe that Mother Gothel from Tangled, is actually just an older version of Snow White's Evil Queen.

It's easy to discover that in The Emperor's New Groove, the only animals who can talk to humans, are the ones who were once humans themselves.

This one is only sad because we'd prefer to think that Boo never grew up and is still happily being visited by her good pal Sulley. If we are to believe this fan theory, then Boo actually grew up to be the oddball witch from Brave. When looking at the witch's cravings, there is clearly one of Sulley. Hmmm...

We hate to say it, but this one adds up. The reason nobody ages in Neverland, could be because nobody there is actually alive. The author who originally wrote Peter Pan, had a brother who passed away at the age of 13. Many believe Neverland was inspired by the author's envisioning of his brother's journey to the afterlife. "To die would be an awfully big adventure”.
