1) His arms are tubes, but can also become elbows, and sometimes can also create shoulders.
2) His flames would be seperate objects, but they need a certain deformer to make them flicker. They also need to always be pointing up.
and most importantly....
3) The way he walks, his base bounces, stretches, and deforms to a million positions. Below are some examples. He can sort of waddle walk, but he also has a jump full of stretch and squash.
So what ideas can you come up with?
