THE AMAZING WORLD OF GUMBALL GRAB BAG 2016: CRAYON WAX ON, CRAYON WAX OFF
Gumball and Darwin Patterson suspect something's up when Nicole and Anais go "school supply shopping" several weekends in a row so they decide to tail the girls, only to discover that they aren't shopping for supplies -- they're battling for them in an underground, tag-team, mixed martial arts tournament! The boys enter the competition themselves when they learn that the prize is the coveted Golden Box of a 1,000 Crayons.
