Jag Tallerson
Jag Tallerson is the head of a very large family of very small creatures that live in the drain of the Mongleys' kitchen sink. After some conflict when the Tallersons are first discovered, they and the Mongleys end up coming to an arrangement of sorts, which involves their interacting with each other as little as possible. Jag is something of a braggart, and sometimes overreaches himself, but he always puts his family first.
