Aoshima

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

History
After eating "bleventeen" packs of Smile Dip, Mabel sees Aoshima in a hallucination. It appears as a flying dolphin with a small yellow bow tie, and two muscular human like 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 blue and white dolphin with a yellow bow tie, four heads, but soon grows an arm out of each mouth. Each arm, in turn, gains a face and a mouth. He makes a grunting noise,much like a real dolphin, instead of talking.

Trivia

 * Aoshima is named after animation director John Aoshima.
 * Assuming John Aoshima uses Japanese pronunciation for his own name, Mabel mispronounces Aoshima.
 * At the end credits of the episode "The Inconveniencing", the cryptogram translates to: Onwards, Aoshima!, which is what Mabel Pines says while she is riding Aoshima in her hallucination.
