Rocky Wrench

Rocky Wrench is an enemy that appears in Super Mario Bros. 3.

Rocky Wrenches are commonly seen on airships, tanks, and naval ships. They are hiding under lids, and will pop up spontaneously, either lifting Mario, or bumping into him.

Rocky Wrenches also appear in Mario Kart DS. As expected, they appear on the course "Airship Fortress", which is modeled after the airships from Super Mario Bros. 3. If on the lid, the kart driver will be lifted up. However, if they run into a Rocky Wrench, they will spin out.
