In their natural habitat, giggle fish approach their victims, speaking in a gravelly tone: "hey kid. Wanna hear a joke?" If the quarry responds in the affirmative, the giggle fish will then proceed to bite off their head (if able) while giggling heavily. So long as the victim refuses to hear the joke and makes their disdain for the idea clear, no harm will come from the giggle fish, though they may appear visibly displeased.
