For the final big bake, Duff Goldman and Kardea Brown encourage the last three bakers to "think outside the cage" and create a zoo cake inspired by the monkey enclosure, the African safari enclosure and the forest predators enclosure. Then, since people love to eat popcorn at the zoo, for the last twist of the season, the young bakers must use popcorn in their zoo cake. The most successful cake maker will earn the title of Kids Baking Champion and $25,000!
