It's "happily ever after" or bust when the bakers try to make fairy tale cupcake pops, then stack cakes in the form of a majestic unicorn.

Space-themed challenges throw the hapless bakers for a loop when they're asked to make cosmic cupcakes and a supersized solar system cake.

The cooks divide and conquer to fill sections of a savory snack stadium before building a cake that looks like a barbecue grill.

The contestants raise the bar with two half-baked "high society" challenges: late-night munchie-inspired pancakes and a gravity-defying tea cake.

The contestants face their fears (with very sharp knives) when they carve an animal out of a watermelon and bend cake into the shape of a snake.

'Tis the season to be scary when the bakers try their hands at holiday cookies before constructing an elaborate gingerbread house.

Five fabulous "Nailed It!" fans visit the test kitchen for a challenge so extra, we had to make it a bonus episode.
