The Skultimate Roller Maze (SKRM) is an annual competition that pits Monster High against various other monster high schools in a roller derby filled with perilous obstacles and mazes. Granite City High, a team of gargoyles and Monster High’s long-standing adversaries, claimed victory in SKRM, seizing the school crest and, with it, the school’s spirit. This loss has caused the school to literally start crumbling, and after the boys suffered serious injuries during the tournament, they decided to withdraw from future participation. In response, the ghouls step up to take the boys’ place in SKRM, donning their gear and beginning their training. However, the boys object, insisting that SKRM is exclusively a boys’ sport and refuse to assist the ghouls in their preparation. Undeterred, the ghouls are motivated to train even harder, aiming to reach the championship game and defeat Granite City High.
