Kaiyukan Aquarium: Pit World A Fun Story of Whale Sharks and Sea Friends I bought this at the Kaiyukan Aquarium several years ago. My child used to play with it when they were little. Pit World allows colorful chips to attach vertically and horizontally on a magnetic stage, creating a fun story with free-flowing imagery. By finding where the chips repel and stick together on the stage, and skillfully stacking them, you naturally develop a sense of balance and concentration. Also, the chips on the second layer mysteriously stick strongly, making it easier to stack on top. It's fun to stack them with a clicking sound. Contents: - Fish Magnets: 24 - Background Board: 1 - Magnet Stage: 1 *All the fish have stickers on them. *The box has some tears. This item has been played with by a child, so there may be minor scratches, etc. Thank you for your understanding.
