Nailed It! Mexico

It's a bird! It's a plane! It's a cookie that vaguely resembles a superhero! Plus, a cake version of Pancho Villa proves to be the bakers' kryptonite.

Class is in session, and the bakers hope to pass their taste tests as they take on school-themed cookies and a hair-raising Albert Einstein cake.

Fairy-tale confections fashioned from cake, waffles and cotton candy find Tinker Bell undergoing a brawny makeover and castles wobbling on beanstalks.

The judges try not to die laughing over ghastly dessert re-creations of Catrina, the queen of the underworld, and a slithering, eye-popping zombie.

The secret ingredient is... saliva? The bakers need some divine intervention while creating cake-pop gods, mole-spiced pyramids and feathered serpents.
