Sandygast is a Ghost/Ground type Pokémon introduced in Generation 7. It is known as the Sand Heap Pokémon.

A Sandygast emerges when the grudges of Pokémon and other creatures soak into the sand after they fall in battle. 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.

The tunnel-like mouth of a Sandygast can suck the vitality from people and Pokémon. Apparently it's a test of courage in the Alola region to put your hand in a Sandygast's mouth.

Sun Born from a sand mound playfully built by a child, this Pokémon embodies the grudges of the departed.
Moon It takes control of anyone who puts a hand in its mouth. And so it adds to the accumulation of its sand-mound body.
Ultra Sun It likes the shovel on its head, so Sandygast will get serious and fight any children who come to take it back.
Ultra Moon If you build sand mounds when you’re playing, destroy them before you go home, or they may get possessed and become Sandygast.
