Cocoron (ココロン Kokoron) is a platform game developed by K2 and published by Takeru for the Famicom in 1991.


At night, a strange animal-like being, Tapir, enters in a kid's house, asking him to help rescuing Princess Lua. Tapir takes the kid to the dream world, and gives him the power to become a hero and venture in the world in search for the princess. Upon defeating the five bosses, he learns from Cocorin that the princess is trapped in a large egg somewhere in the dream world.

Upon finding Princess Lua, she reveals that Tapir is actually a baku, a dream eater that created the dream world to eat the imagination of the kid he brought. To rescue the beings from the dream world and himself, the kid must defeat Tapir. After rescuing Cocoron, the heroic kid defeats the dream eater. Tapir is sealed inside an egg and Cocoron sends the kid back to his house.


Main characters

  • Kid - The protagonist, an unnamed kid that Tapir brought to the dream world to rescue Princess Lua. In the dream world, Tapir gives the kid the ability to become a hero created with his imagination. Later five heroes (which also are the kid) join him.

  • Princess Lua (ルーア姫 Rūa Hime) - The princess of the dream world, who was kidnapped by evil forces. After defeating the five bosses, Cocorin informs the player that she is trapped in an egg somewhere between the stages.
  • Cocoron (ココロン) - The titular character, a fairy from the dream world that was kidnapped by the evil forces. She is rescued in the final stages.
  • Cocorin (ココリン) - Cocoron's younger sister. She was trapped in the Fairy Forest and later replaces Tapir in assisting the player.

Playable characters

The player's characters are created by combining Faces, Bodies, and Arms. Each part has a Weight value that influences movement speed and jump height. Faces and Bodies also affect the maximum Life Points, while Arms determine the Attack Power. After selecting the parts, the player can name the character and test him.

The player starts with one character, but when one of the five bosses is defeated, a new character can be made. Faces can Bodies can't be reused (unless it has a different visual), but Arms can be given to any amount of characters. When Princess Lua is rescued, the player's characters will be kidnapped by the final boss, except for the one currently in use. They are rescued one by one in the final stages, becoming available again.


Faces are the character's head. While they have no special effect on their own, they affect what the Super Item will do when it is taken by the player. Each Face has three different visuals, giving the player a total of 24 Faces.
