Palossand

Palossand is a Sand Castle Pokemon. Possessed people controlled by this Pokemon transformed its sand mound into a castle. As it evolved, its power to curse grew ever stronger. Buried beneath the castle are masses of dried-up bones from those whose vitality it has drained.

Trivia

 * When Ash puts a Rotom on Sandygast's head as a replacement for the missing shovel, it evolved into a giant angry Palossand.
