Boobafina makes an appearance in the episodes "Storytelling" and "Come Along With Me." She has a crush on Mr. Goose, and to complicate matters, Mr. Fox is infatuated with Boobafina, and they kiss against their will, courtesy of Finn. She becomes upset because she feels Mr. Goose will now never have feelings for her because she's been "soiled." However, at the Rite of Forest Justice, it is revealed that Mr. Goose had been wanting to date her for years. The two were both happy to know of each other's affections while Mr. Fox, on the other hand, was told to move on, and he admits it is for the best. Her relationship with Mr. Fox is now unclear.
In "Together Again", Boobafina is said to have been reincarnated as a tugboat.
As stated by character designer Andy Ristaino, she is not the same duck that appears in "Conquest of Cuteness".
