Marine and his friends went out for a day of fun at the Jelly Land Amusment Park. It was a fun day, lots of laughs. It was a real riot until a mysterious jester showed up. The Jester changed Marine and his friends into puddles of slime. Now Marine must find his way through the Jelly Land Amusment Park to find his friends, so they can battle the Jester and break his curse.

Along the way, you’ll travel through eight worlds. The player has some choice in the order to play the levels through. As you play, you’ll rescue Marine’s friends. Each of them has a special talent, which will enable you to find your way through various puzzles, in order to find all the secrets. Most of the levels are pretty easy, but the bosses will present a decent challenge trying to defeat.

This game is the unreleased sequel to the platformer game Jerry Boy.
