Mighty Mighty Monsters in Halloween Havoc (2013)

Get ready for one scare tomb many, as Frankie, Vlad, and Gunner - three awkward misfit monsters - come face-to-face with their greatest fear yet: High School. Forced to attend an all human school, the monsters must learn the ins-and-outs of being scream-agers and surrender to the lifestyle of the other ghouls and boils. But when Frankie decides to go full human, Vlad and Gunner must spook some sense back into their friend and prove once and for all there's nothing scarier than being human!
