Gocchi serves as a secondary antagonist, relentlessly pursuing the protagonist Punon alongside the carnivorous dinosaur Rucchi. They attempt to capture Punon early on, but their pursuit is interrupted when Tyrano accidentally frightens them away while reaching for fruit. Later, Gocchi and Rucchi ambush Punon, only for Tyrano to intervene and rescue her during the attack. Following these failed capture attempts, Punon taunts Gocchi and Rucchi on two separate occasions, first shaking her rump at them and later performing an eyelid pull taunt.
