The pikmin has armature bones in the spine and the leaf. The limps has no bones, but I will add them for him to run. The eye balls are missing for a reason. The pikmin can move the head and leaf, distorting the skin. The armature can track a object. He seems drunk. Applying Stretch to constraint, pikmin’s head shrink and stretch as rubber. The Pikmin model is from Pikmins | Blend Swap made by Temujin.
