Synopsis
It's Halloween, and the Ranger Teens are helping out at the Youth Center. Tommy escorts a group of kiddies dressed like Rangers out to trick-or-treating, only to have them turn out to be Putties. He's no match for them, and ends up sucked into the Dark Dimension. There, facing a Tombstone monster, Tommy is alone against a graveyard filled with formally-destroyed monsters!
