Planktuiyii is a weird clone of Plankteegee. He was created after Plankteegee stared in the mirror. Out came Planktuiyii, who is the Guiyii of Plankteegee. He joined the Plankteegee and Plenktun Army, and works for them. He is against Malleo and Weegee, and frequently tries to kill them. Oddly enough, he manages to get along with Guiyii.
