Grubby (トゲラ) is an enemy in Super Mario Land 2: 6 Golden Coins. It is the matured form of a Unera. Grubbies have spikes protruding from their body, protecting them from jump attacks. Mario can defeat a Grubby by either hitting a block they are on top from below or by touching one while under the effect of a Starman.
