Kero Kero Keroppi no Daibouken

Kero Kero Keroppi no Daibouken is based on the popular Sanrio character Keroppi. Released on the Nintendo Family Computer console in Japan in 1991.

Big Adventure is a children's puzzle game where Keroppi must rescue his girlfriend Keroleen who is locked up in a castle.

To do so, he must solve the action based puzzles in seven differently themed worlds with four different types of stages (the surface of the maze, flying a plane, a Reversi-like level, and through a field of lava).
