Palpatine's mole was a very big mole that was found on his penis. It was so huge Darth Small camped at the top once, but threw up so many time he left due to the very disgusting view. Palpatine thought that the vomit was apple sauce, and told everyone that he could pee apple sauce. Several months later, Luke Skywalker confessed that he saw the mole move. Scientists examined it on 19 BBY and found out was a live alien. People avoided him ever since.
