General Adenarius Sestertius Pinchkin III is a penguin commander featured in The Pinch who Stole Christmas. He is the leader of the penguins that abducted various snow imps, Jack Frost, the Queen of Snow and Nicklaus as part of a plot to take over the world. After the imps, Jack and the Queen had been freed with the help of an adventurer, Pinchkin's Snowverload monster and two of his lackeys fought a snow battle against the Queen's legion of enchanted snowmen, but lost. As a result, Pinchkin was trapped in a huge snowball, unable to move. He later attempted to convince the adventurer and their friends that he had just been trying to spread Christmas joy, but this was revealed to be a lie.
