Bufo

The BUFO makes an appearance in "Wizard." They are a group of tadpoles that live inside a frog. They bestow Finn and Jake with wizard cloaks (which Finn sees as a dress and tucks it into his shorts so he wouldn't be embarrassed). They trick Finn into achieving every level of wizardry until he became a master, then condemned him, telling him he had to make a vow, and Finn accepted without even knowing what vow he had to make. Finn, upon accepting the pledge, was led to a room where he would protect the wizard training facility from a meteor with the Old Wizards for the remainder of his life, using the powers to keep the meteor away. At the end of the episode, the BUFO begins to renounce all magic, but Finn interrupts, telling them it is unnecessary to quit his job, and that he only had to stop taking credit for ideas that weren't his. He took credit for that idea. It is known that one of their names is Leonard. His name was revealed because he couldn't keep up with the talking by the other BUFO. BUFO also appears as a contestant in "Wizard Battle."

Appearance
The BUFO live inside of a toad (which is likely their father) and can only be seen when the toad's vocal-sac is fully expanded. The toad often portrays the other BUFO's emotions. The BUFO themselves are teal tadpoles with small purple wizard hats. There are nine of them, and they all try to speak in unison.
