During a sudden attack by an evil force, the peaceful kingdom of Moberry has been invaded. The player takes control over Charly, an alligator with a mission to defeat the dragon warlord Basso Gila. To achieve this, five areas must be conquered, each containing three or four levels.
These levels can be tackled in any order and come in various forms such as land, air, cave, or underwater environments. However, Charly is not alone, as he faces numerous enemies that try to harm him. Contact with these enemies or environmental obstacles will cause a heart from his health bar to disappear. Charly can also defeat himself by hitting enemies with his tail, which has varying ranges depending on the power meter.
The goal of each level goes beyond simply reaching the exit and defeating occasional bosses; it's also about opening all treasure chests along the way. These chests contain random power-ups such as health refreshments, bonus points, power-ups that can kill everything on screen, or a bomb that will destroy all on-screen enemies.
