Plok can launch any of his four limbs (two arms and two legs) at will to damage enemies as projectiles from his arms and feet. While a limb instantly returns to Plok's body if it hits an enemy, it takes longer if it does not collide with anything. Limbs can also fire through certain barriers like rock pillars. The only limitation is that he cannot shoot limbs while doing a somersault. In later levels, some puzzles involve having to "sacrifice" one of Plok's limbs to activate scenery-changing targets. Once a limb hits a switch, it is placed on a hanger that's usually next to the target; some targets also require certain limbs. Once Plok is limbless, he moves by bouncing and becomes harder to control.
