If you charge up the Peanut Popgun for too long, it will explode, briefly stunning you but also damaging nearby opponents. After landing on an opponent with the Monkey Flip, jump out of it or continue attacking using the attack button. Hold down the special attack button to charge up his Rocketbarrels, aim with the Control Stick, then release to blast him. You can only have one banana out at a time. No more "glide tossing" for you!
