Made for my Star Wars-obsessed son's 6th birthday. 3 or 4 (can't remember) stacked 6" rounds topped w/half 6" ball pan. PVC structure thru for legs, cov'd in RKT and fondant (not well). Cov'd cakes in fondant & used butter knife to "carve" panels. Painted w/watered-down gel tint. Cake SANK overnight, so we called him battle R2-D2.
