Sandworm

The Scythe-armed Monster (referred to as Big Scorper in the game's European website despite this being the name of an unrelated enemy, named SandWorm in the Prima Games guide) is a boss in Wario World. It is the boss of Greenhorn Ruins, and the second of the three bosses in Excitement Central (the others being Reptilian Goliath and Dinomighty).

The Scythe-armed Monster is fought in a large sand pit that continually pulls Wario towards the center. Its main attack is spitting spiky balls at Wario; Wario can easily damage it with repeated punches. The Scythe-armed Monster cannot be stunned; when it loses one of its health skulls, it instead slashes after Wario with its scythe-like hands. Also, the Scythe-armed Monster may 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 with more powerful moves, including slicing Wario with its hands. Defeating the Scythe-armed Monster gives Wario access to Dinomighty.

The Scythe-armed Monster also appears in Pecan Sands as a regular enemy, where its attacks are a bit faster, but it is fought and defeated in the same way.

Trivia

 * The Scythe-armed Monster, along with Dual Dragon and Red-Brief J, are the only bosses that don't require Mad Moves to defeat, as they can't be used at all; the Scythe-armed Monster can't be grabbed and carried, and there is nothing to pick up around its arena.
 * Its tactics and arena are similar to Squizzard and his arena from Super Mario Galaxy 2.
