Chuck is a poor bird who appears caged in the Jazz Jackrabbit series. If you free him (only in single player or coop mode), he will help you by firing enemies until you lose health, after what he leaves.
In Jazz Jackrabbit 1, there’s a bonus level where you must play as Chuck, with the capacity of shooting.
In Jazz Jackrabbit 2, using JJMORPH or a special event, you can become Chuck. It is used in Labrat secret level. Sadly, you can’t fight or shoot…
Eat your lima beans, Johnny.
