The Shisaku-gata Spanner (試作型スパナ[1] Shisaku-gata supana?, lit. "Prototype Model Spanner") is an enemy that appears in Sonic Rush Adventure. They are a type of Badnik created by Dr. Eggman and Dr. Eggman Nega. In the game, they can be found in Machine Labyrinth and Hidden Island 10. Each one carries a spanner in its right hand.


When the player encounters the robot, it defends itself by swinging his arms vigorously while turning its body.
