Chum

Chums are a type of Salmonid, the main antagonists of Salmon Run in. Chums are the most common form of Salmonid, and use a frying pan to attack inklings. They are not very tough individually, but they can pose a threat in large numbers or against Inklings that aren't paying attention to their surroundings. During the Salmon Rush Chums become very fast and deady, and they come in huge numbers.
