Mudflap and Skids are known in Transformers Revenge of the Fallen as the “Twins”. Usually, siblings in Transformers means cheap reissued toy moulds in new colours, but in the case of Transformers Revenge of the Fallen, “twins” means different moulds, different vehicle modes; almost an entirely different toy, in fact!

Consisting of Highjump, Mudslinger, Powertrain, and Tote, the Autobot Off Road Patrol was released concurrently with both the Race Car Patrol and the Air Strike Patrol. With the Micromasters sub-range initially returning to aircraft equal Decepticons and cars and trucks equal Autobots, it meant, for the moment that the Autobots outnumbered the Decepticons two to one.
