a two-part adventure from the recent animated children's series plus another episode. three of the baddest mamajammers, throttle, vinnie and modo, are back on earth and ready to rumble. they're hip, tough, funny and, above all, feel the need for speed. they also have hearts as big as their helmets. in 'the adventure begins: part 1' the mice need to prevent the evil catatonians from capturing the regenerator, which could save mars from drought because it has the ability to convert dirt into any substance needed. 'the adventure begins: part 2' sees the last remaining regenerator destroyed and the mice having to take the creator of the regenerator, general stoker, to planet earth to find the components to build another one. finally, in 'it's the pits' the mice encounter the biggest, baddest baddie of them all, the pit boss, and another band of enemies to fight, the plutarkians.
