Clumsy Ninja

Gameplay centers around training the ninja and improving their "ninja skills". The player can train the ninja by doing certain activities such as: playing hide and seek, playing on the trampoline, training with a punching bag and many other activities to earn experience (xp). As the ninja improves his skills he earns new belts. Another big part of the game is traveling the country and completing quests, doing so will unlock new items that can be used to further train the ninja, along with unlocking more of the game's story.

The story is told from a third person perspective by the ninja clue book. The main aim of the game is to save Clumsy Ninja's training partner and friend Kira from Hori-Bull, who aims to find the Dragon Medallion. Kira finds the Dragon Medallion before Hori, but loses it as Hori-Bull weakened her with a jelly potion to make her limbs weak. He then traveled to the temple region, bringing Kira with him.

Kira manages to write a warning on one of her diary pages and give it to her squirrel friend, who soon brings it to Clumsy and friends. Clumsy Ninja, Lily, the chicken, the squirrel, and the Sensei arrive to the temple environment/area to find Kira and save her from Hori-Bull. Clumsy, with the others, also find Kira's sword. They unlock the dojo, only to find Kira and Hori-Bull as stone statues.
