Banishback appears to be just a big, round purple cloud with a wide, evil smile. They make an off-key whining sound that gets louder as they come closer. There are several sizes of Banishbacks, but they all look extremely similar.
Banishback appears exclusively in Stage 4 of Volcano Valley. They do not actually attack; instead, they serve more as hazards than enemies. If a Kirby touches one, it sucks the heroes in and takes them back to the beginning of the room. After being taken back to the start of the room by a Banishback, blocks, enemies, and shells regenerate. Banishbacks cannot damage the Kirbys.
Banishback's mobility is rather slow, but the larger ones can take up a great deal of space. The enemy is able to pass through walls (if they go through walls on their route,) as well as disappear and reappear. Banishbacks are present on land and underwater.
Banishbacks can be defeated by Jumbo Candy. The upper route in Stage 4 is set up so the player can defeat them that way.
Banishback is a combination of the words banish and back, referring to Banishback's ability to send the Kirbys to an earlier point in the level.
- One of the checklist tasks requires the player to complete Stage 4 of Volcano Valley without coming into contact with a Banishback, and without using the shortcut.
