The Cage.

When Mr. Corneille (the computer-pixelated frog geography teacher first seen on "The Others") lies to the Band-Aid school nurse about how he got injured, Gumball and Darwin think Mr. Corneille is a mixed-martial artist and convince him to go up against a Russian fighter named Joao in a cage match to raise money badly needed for the school.
