After customizing a character's gender and name, the player helps the Maboo Tribe of the Amazing Island remove a possessing spirit known as the "Black Evil".
By completing courses, the player gains Vision Orbs, which drives off the Black Evil, restores portions of the Island, and earns them new abilities and items to customize their monster partner.
New frames are gathered from completed Courses and more advanced drawing tools such as a Stamp or Resize are gained from Vision Orbs.
Patterns are textures that drawn on the body that can range from materials e.g. Glass, Rock, Lava; skins e.g. Dog, Cow, Parrot; or outfits e.g. Ninja, Santa, Cute Robot.
Every aspect of a monster—frame, accessories, actual drawn body shape and thickness—affects its stats: Speed, Mental, Power, Stamina, Weight, Element, and Class.
Amazing Island offers multiplayer options, where two to four players can compete on the Courses or link up in the Monster Cards minigame.
