Haguhagu remains in its start position on the map, never moving. If there is a free tile space next to it, it will create a Soft Block on that space. It takes a few seconds to generate a Soft Block, and Soft Blocks that are beginning to appear cannot be destroyed. If Hagehage is entirely trapped within Soft Blocks, it will sleep until its barrier is broken. It will harm the player on collision.
Upon defeat, Haguhagu becomes a biological Egg. In Battle Mode, it can be found randomly in Eggs that are uncovered in Soft Blocks, but only after the password 0164 has been entered.
Players who ride Haguhagu can destroy all Soft Blocks on the map with a single press of the Y button.
- The name "Haguhagu" comes from the Japanese word "hagu", roughly meaning "to remove". This refers to Haguhagu's special ability.
