Bee

The Bee was seen in the episode "Evicted!" when Jake, along with Finn, tried to move into its hive by sticking his foot into the entrance. The bee vomited honey on both of them to scare them away. Later, at Finn and Jake's cave party, the bee can be seen flying into Mr. Cupcake's frosting and apparently getting stuck in it.

Trivia

 * The bee appears in the closing credits, although it seems much happier.
