もずポン - Japanese spelling
MozMoz-kun, a kid with a bowl cut, has to break all the eggs on the screen by bouncing a round, pig-like animal named Butasan on his head. Once the eggs are cracked, baby chicks fall out of them, which he must then grab. The more baby chicks he catches in a row, the bigger the bonus points he'll get for them. But if he misses just one, the streak is broken and he has to start again. Once he collects twelve baby chicks, the "Baby Chick Roulette" on the side of the screen will start up. This roulette can earn you bonus points, special power-ups, or other bonuses!
There are also special eggs in the playfield. Some eggs need more than one hit to be cracked open; a Rainbow Egg will give you the chance to use two Butasans at the same time; and a bomb will destroy any eggs that are around it when it blows up.
But you have to watch out for Josephine; if you let her catch you, you won't be able to move for a few seconds, which may cause you to lose your Butasans!
The game contains a total of thirty-two levels to beat. Once you've cleared them all, you'll get to meet The King of Eggs...
