Aoshima

Aoshima is a creature seen in the episode "The Inconveniencing."

History
After eating what Mabel says are "bleventeen" packs of Smile Dip, she sees Aoshima in a hallucination. It appears as a flying dolphin with a small yellow bow tie and two muscular human arms. After spinning around, it grows another dolphin-like head and two more muscular human arms. On each palm of its hands are dolphin faces, which shoot rainbow-colored rays from their mouths. While doing so, a car alarm can be heard.

Physical appearance
Aoshima is a hallucination-induced monster, and as such, looks extremely odd. He appears to be a dolphin with four heads, but soon grows an arm out of each mouth. Each arm, in turn, gains a face and a mouth.
