A Sandygast emerges when the grudges of Pokémon and other creatures soak into the sand after they fall in battle. In essence, it’s a possessed lump of sand!
If you heedlessly grab a Sandygast’s shovel, you’ll fall under the Pokémon’s control. A Sandygast uses its power to manipulate children into gathering sand to increase the size of its body. If a Sandygast loses its shovel, it may put up a tree branch, a flag, or another item in its place. These Sandygast are wanderers in search of their own shovels.
