Sandworm is a scythe-armed monster that vaguely resembles an antlion larvae it is brown in color, with two yellow horns on it's head, eight rows of teeth in it's mouth on top and bottom it also has gray pincers and a partially closed eyes the top part is closed while the bottom is open.
Battle
Sandworm is fought at the end of Greenhorn Ruins in a large sand pit that continually pulls Wario towards the center. It's main attack is spitting spiked balls at Wario; Wario can easily damage it with repeated attacks. The Sandworm cannot be stunned; when it loses one point of health, it will instead become temporarily invincible, and either slash after Wario with it's scythe-like arms, or burrow to the center of the arena and start spitting many spiked balls in random directions.
When this happens, the sand pit pulls Wario in much faster. If damaged enough, it will also strike back by slicing Wario with it's arms.
Sandworm is later encountered in the level Pecan Sands this time as an enemy it behaves just like it does during its boss fight making it the only boss in the game to appear as a enemy.
