I Flushy my Brushy is a short. K'nuckles tells Flapjack that an adventurer never brushes his teeth. Flapjack throws away his toothbrush and has fun with K'nuckles. Bubbie then kicks Flapjack out and finds that his teeth are dirty!
This is Bubbie's first speaking role.
K'nuckles teeth can be removable. He later did that in Fish Heads.
Most of these scenes appeared in the song, Your'e Beatuous.
