The Munchables are hungry creatures, taken over by Don Onion and his evil space pirates. The only hope for the planet's survival is to eat the most enemies and grow large enough to defeat Don Onion and the 8 Enemy Bosses. The more you eat, the bigger you get, and you're going to have to be big to beat Don Onion and his space pirates.
You can power-up yourself to eat the array of vegetables, fruits, and even porcupines that are in your way! The planet depends on the Munchables for survival. No pressure.
