Biker Mice from Mars (2006) 1x13

Rump hires the felonious Flare to create a landslide inside Stoker's cave-bound laboratory, leaving General Stoker trapped inside and his research vulnerable to discovery. It is up to the Biker Mice to don spelunking gear and rev up their cave-cycles to save the General and his work before Rump and the Catatonians can get their paws on him.
