The film opens with a Spartan elder inspecting an ugly, talking baby (an ogre from Shrek 3); it is abandoned to die for its deformity. A second baby with dark skin is adopted by Brad Pitt and Angelina Jolie. Baby Leonidas is then inspected, having a six-pack, biceps, and beard from birth. He is accepted as a Spartan and prepared for kinghood through his childhood training, from fighting his grandmother to enduring torture (a la Casino Royale). Leonidas (Sean Maguire) is then cast out into the wild, and survives the harsh winter and a gangsta penguin (Happy Feet). Returning a king for his inauguration wearing a penguin skin hat, Leonidas sees Margo (Carmen Electra) erotically dancing and asks her to marry him, to which she responds by giving him the combination to her chastity belt.
