Isle Delfino Police
The Isle Delfino Police, also known as Pianta Police, are the principal law enforcement agency in the island of Isle Delfino during Super Mario Sunshine. The officers arrest Mario because they suspect he is responsible for polluting Isle Delfino with graffiti, when it is actually Bowser Jr. (disguised as Shadow Mario). After Mario is put on trial, they order him to clean up all the goop on the island, a task which he must complete before he is allowed to leave. The Isle Delfino Police look very similar to normal Piantas, though they wear blue shirts, as well as police caps that have a Shine Sprite logo on them. The officers are blue and orange, and the blue one has a black mustache.
Near the beginning of the game, when Shadow Mario tries to kidnap Princess Peach and Mario chases him, they run right by the Isle Delfino Police, who seem oblivious to this; for the entire course of the game, they are under the impression that Mario is responsible for the pollution and continue to tell him not to slack off.
In the Super Mario Mash-Up Pack in Minecraft, Butcher Villagers are replaced by an Isle Delfino Police officer.
