I just got Snarlag yesterday, and accidentally found out how to transform his torso correctly. First, flip the red painted piece that tabs onto his crotch infront of the upper grey piece. Then, allign the grey piece to fit inside the torso. The cut out part was not only for the dino legs. This should securely fit together with the red peice in the torso. The finished product is a much nicer, more compact torso, with everything inplace, and no dino head gut.
