This is Baymax, the inflatable robot from Big Hero 6, along with a pair of rocket boots with a flame effect. The model is made up of extruded, revolved, swept and lofted bases. A complicated spline geometry was used to make the body look as bulbous as the reference picture in all of the right places. The model is intended to be as satisfyingly squishy (limbs pressed together, etc.) as the Baymax character is.
