Spinwulves quickly run back and forth, following the protagonist as he moves around the screen. They tend to run fast on slippery ground but often fall into pits. They have two hit points, deal half a damage point and drop a green gem worth 10 gold when defeated.
- The Spinwulf's idle animation (sitting and flailing its tail) is only seen in the credits since they directly start running around once they appear on the screen.
- Their model in the game's file is named "Dire Wolf".
- Shovel Knight refers them as "snow wolfes" when speaking to Toader.
