Sandworm

The Big Scorper (named SandWorm in the Prima Games guide) is a worm-like 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).

Big Scorper 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. Big Scorper cannot be stunned; when it loses one of its health skulls, it instead slashes after Wario with its scythe-like hands. Also, Big Scorper 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 Big Scorper gives Wario access to Dinomighty.

The Big Scorper also appears in Pecan Sands, where its attacks are a bit faster, but it is fought and defeated in the same way.

Trivia

 * Big Scorper, 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 Big Scorper can't be grabbed and carried, and there is nothing to pick up around its arena.
 * Big Scorper bears a close resemblance to Junior the Giant Klaptrap.
