>>30276486>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. "Skin"s an odd or poor choice of words, but it's a part of the Sandygast's body in the same way other ghosts possess stuff that makes up their body.
