Three further adventure from the recent animated children's series. 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 'Changes', General Stoker has turned into the mad 'Stoker Rat' and loose on the streets of New York where Rump captures him in a bid to make him build another Regenerator. 'The Tender Mouse Trap' sees the mice convert their bikes into Swamp-Cycles in order to save a female mouse in distress. But is she really needing their help? Whilst in 'Break Up', Throttle is promoted and so returns to Mars to take on his new command. However, Modo's nephew shows he was probably not the best choice to fill Throttle's shoes.
