The Amenbo is one of the smallest Badnik models that Dr. Eggman has ever created, being based on water striders. It has a cyan-colored body with metallic spindly legs. Also, located on the rear of Amenbo is a sizable fan used to navigate the surface of the water.
The Amenbos appears exclusively in Tidal Tempest. In gameplay, they will attempt to shoot small flashing projectiles at the playable character, although they do so rather sporadically. The worn down version of the Amenbos in the Present and Bad Future is not very different from its pristine version, except the fan on their bodies is broken, they move slower, and they never fire projectiles.
Amenbos are rather rare enemies, as they only appear on the surface of large water sections, something which Tidal Tempest has very few of. Otherwise, Amenbos can easily be defeated with a simple Spin Jump. Also, like every Badnik in the game, the Amenbos are powered by Little Planet flower seeds which will pop out of them when they are defeated.
