The crew confront Santa, and Leela presents him with what she believes to be a logical paradox intended to destroy him. Unfortunately, Santa proves immune to paradox, and he takes off after them with a missile launcher. The crew escapes the fortress, and is about to leave in the ship, but Santa grabs the engine and prevents the ship from taking off. The heat from the engine melts the ice under Santa's feet, and he sinks in the ice, which refreezes around him.
