"Coco's got competition" is an ad created by cereal brand Surreal, cleverly playing with word association, a nod to one of Kellogg's most famous cereal lines, Coco Puffs. Coco is the name of the ape and mascot that's on the Coco Puff packaging, so "Zero sugar, zero monkey business" is a brilliant way to emphasize that Surreal's Cocao Cereal is the better choice, as a lot of people associate cereal with loads of sugar.
