Bonk can also collect pieces of meat as power-ups; these lend him special abilities and make him stronger. There are three stages of a power-up: his normal self, a second stage during which he can stun enemies by pounding on the ground, and a third stage where he becomes temporarily invulnerable. Meat can be found in two varieties: big meat and small meat. The effects of meat are additive but wear off over time. A small meat gives Bonk the second stage of meat power and a large one takes him to stage three. Eating a small meat while in stage two will also put Bonk into the third, invincible stage of meat power. When the third stage effect wears off he returns to the second state and remains there for a while before turning back to the regular Bonk. Eating either size of meat while in the third stage of meat power-up will reset the timer on Bonk's meat power.
