Finn has a fish bowl as a head but with eyes mouth and human body hes very cheerful and often makes puns he wears an orange life jacket and white pants with white shoes the water doesnt spill from him though which is strange anyway hes your only friend who lives with you in one house and you do everything together hes 12 since hes glass he can crack and break easily hes from dandy's world so its normal for him to look like he looks
