Welcome to Booh Town, where a fellowship known as The Monsters Squad, valiantly thwarts the snares of a nefarious scientist, Hugo von Viktor, intent on spiriting away little monsters to his human realm, seeking to validate their existence. ​But Hugo Von Viktor's interest wasn't purely scientific. He knew the ancient legend of Booh Town: once a year, on the night of the Crimson Moon, "The Monsters Squad" could transcend their monstrous forms. For a single night, they could become human.
