One of the few episodes in which the waving snail is absent.
The intro montage features Finn, Jake, and other creatures/animals in different than usual roles. For example, Finn is seen kissing a penguin in the beginning, Princess Bubblegum is riding a creature other than Lady Rainicorn, Jake rides Finn (who has stretchy arms and legs) through the distant lands mountains, and the song identifies Finn and Jake as "Jake the Caterpillar" and "Finn the Flower." The changes align with the content of the episode, where Finn and Jake appear as caterpillars, birds, and bacteria.
