My 3-yr-old brother's friend once told him that the "king alligator" lived in people's walls. There was a little hole in the bathroom wall made from the doorknob (it was near the toilet). So one day we hear him screaming and crying while on the toilet. I ended up spending the next 239482734 of his bathroom trips sitting outside the bathroom door while he cried, telling him there was no such thing as the "king alligator" and that he didn't live in our bathroom wall.
