After eating "bleventeen" packs of Smile Dip, Mabel sees and rides Aoshima in a sugar induced hallucination, claiming "the future is in the past". 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, one from each mouth. On each palm of its hands are dolphin faces, which shoot rainbow-colored rays from their mouths. While the creature is doing so, a car alarm can be heard.
Aoshima is a hallucination-induced monster, who appears to be a blue and white dolphin with a yellow bow tie and four heads, but can grow an arm out of each mouth. Each arm, in turn, gains a face and a gaping mouth, which makes dolphin sounds and emits rays.
- 105. "The Inconveniencing"
- The word "bleventeen" as said by Mabel has the letter "b" in a Three-Letters back cypher the same as "BEWARB" in "Tourist Trapped".
- Aoshima is named after animation director John Aoshima. Tyler Chen came up with the idea for the name.
- In the end credits of "The Inconveniencing," the cryptogram reads "Onwards, Aoshima!" a reference to Mabel's line earlier in that episode.
