Editing Proto Piranha

Gatekeepers first appear as recurring bosses in the early parts of ''[[Super Mario Sunshine]]''. {{anchor|Generators}}In this game, Gatekeepers are all connected to solid, undulating, smoking masses of goop referred to as '''Generators''',<ref>{{cite|author=Hodgson, David S J; Stratton, Bryan; Stratton, Stephen|title=''Super Mario Sunshine'' Prima's Official Strategy Guide|page=11|date=September 3, 2002|publisher=[[Prima Games]]|language=en-us|isbn=0-7615-3961-1}}</ref> which cannot be cleaned normally. Additionally, some Generators spread goop to the surrounding area, preventing it from being cleaned permanently until the Gatekeeper is defeated; however, despite their name, not all Generators do this. Initially, Gatekeepers hide within the Generator, emerging only when the Generator is sprayed with [[water]]. Once a Gatekeeper has emerged, it sways back and forth while opening and closing its mouth. To defeat it, [[Mario]] must use [[F.L.U.D.D.|FLUDD]] to spray water into its open mouth some number of times. If Mario sprays one while its mouth is closed, it merely shrugs the attack off. If not dealt damage for long enough, it retreats back into its Generator. In all their appearances, structures are submerged in the goop beneath them, and the Gatekeeper must be defeated to release them.
