Gulp is a weak ally. He is nothing more than a fish, though he keeps a smile on his face. He has all the power of a fish, which is not much, and has to flop around while on land. He is usually found early in a game (if at all), but is quickly replaced.
Gulp has a few Water-based attacks, but as he has not been seen in a while, it is unknown what they actually do. In essence, Gulp is similar to a joke character. He is friends with Rolo and Fishy
