Sandster can trap its prey by trapping them in quicksand. If people or Pokémon that are stronger than it see it, it will use the sand to make itself look bigger and stronger. If that doesn't work, it will use Sandstorm and flee.
Sandster are very mischievous Pokémon. They like to scare other Pokémon and take food or shiny objects away from people and Pokémon.
Likes to live in deserts, especially sand dunes, so it can trap prey in a quick sand trap.
Hiding in dunes, Sandster often trips Pokémon and people alike by creating small bumps of sand, then attacking them whey they're down.
