This is the ‘Classic Space Baby Mobile Rocket Transport Mech’, or C.S.B.M.R.T.M. for short, a triple rocket transportation and launch system that can transform into a giant space-baby mech. Because shut up, that’s why.
Angus MacLane is the owner / father responsible for this mildly terrifying Classic Space roving automaton, and there’s more of his otherworldly insanity to see at his photostream. Pack some giant space diapers and head to lunar daycare via the link in the text above.
