Sandworm

The SandWorm is an evil, worm-like boss in Wario World, fought in a large sand pit that continually pulls Wario in the center. SandWorm is the boss of Greenhorn Ruins. Its main attack is spitting spiky balls, but if damaged enough, it will strike back with powerful moves, including slicing Wario with its scythe-like hands. It is quite easy, though, as all Wario must do to damage it is give it repeated punches.

SandWorm never becomes stunned. But when one of its health skulls gets chopped off, it slashes after Wario with his scythe-like hands. Also, SandWorm may dash to the center of the arena and start spitting many spiked balls in random directions. When this happens, the arena pulls Wario in much faster. The player will have to stay away from its sand trail, and sooner or later, it will be deafeated, giving Wario access to Dinomighty.

SandWorm is the second of two mini-bosses in Excitement Central, Greenfist being the first.

A SandWorm also appears in Pecan Sands. In this fight, it's a bit faster, but otherwise unchanged.

Trivia

 * The sandworm is an actual generic creature in the Real World.
 * An issue of Nintendo Power erroneously stated that Mummipokey (an undead Pokey, and therefore possible Skellokey or Pokey Mummy) is a sandworm. This statement was probably referring to the actual creature, though.
