The Tidal Plant Zone Badnik is an enemy that appears in the Sonic the Hedgehogø series. It is a mass-produced, sea snake-based Badnik model created by Dr. Robotnik. It is not named in any official instruction manual or supplementary material.
These Badniks resemble sea snakes. They have three spherical body segments making up their body, similar to the Caterkiller or Crawlton, and possess an orange and white color scheme. They also have mostly black eyes with cyan irises.
In Sonic the Hedgehog Triple Trouble, these Badniks only appear in the underwater areas of Tidal Plant Zone, and are the only type of enemies encountered in the entire Zone. In gameplay, they swim back and forth in wavy patterns with three body segments following their head segment. The segmented parts have electricity running through them, similar to an electric eel. As a result, attacking these segments will result in the playable character taking damage. To destroy this Badnik without taking damage, the player has to hit them on their heads.
Like other Badniks in the game, they do not have Animals as an energy source that they release upon their defeat.
