This Saturday, NBC and DreamWorks will showcase the Halloween special Monsters vs. Aliens Mutant Pumpkins from Outer Space, one year after it debuted on the USA Network. In the special, the monsters join Susan (Ginormica) at her home for Halloween celebrations. Susan spends time with her parents, while the others trick-or-treat. However, that wasn’t their true intention. The Monsters came to destroy mutant pumpkins hidden in the Halloween decorations! When Dr. Cockroach discovers the mutants are after the candy – which they eat to grow larger – the monsters and costumed children must fight them off. Nothing says Halloween like a Monster and Mutant throwdown! TOON in on Saturday, October 30th, at 8:30 — immediately following Scared Shrekless.
