This is an original design for a Lego Transformer Snowmobile. It goes from a snowmobile in vehicle mode to a robot. To transform it, all you have to do is bend, pull, or twist on certain pieces. No pieces have to be removed or added to transform it. To fold the legs out, pull on the connector between the upper and lower torso. This part is the hardest, but the plus part of the connector should allow it to slide without coming apart. All the other bends are self-explanatory.
