The Story

What the Pokédex says

  • Legends: Arceus

    Eats beach sand for nourishment. Should one Gastrodon encounter another of a different color, a fierce battle will inevitably ensue.

  • Shield

    The softness of its body helps disperse the force of impacts, so although its body is uncommonly squishy, it’s also surprisingly resilient.

  • Sword

    Its search for food sometimes leads it onto land, where it leaves behind a sticky trail of slime as it passes through.

  • Ultra Moon

    Their shape and color change, depending on their environment and diet. There are many of them at beaches where the waves are calm.

7 more entries from older games
  • Ultra Sun

    Long ago, it had a shell on its back. There’s now a vestigial plate on its back that’s hard but thin.

  • Moon

    Plankton, invisible to the naked eye, is its main food source. It comes onto the land periodically, but the reason for this is not known.

  • Sun

    It has strong regenerative capabilities. Even if parts of it are bitten off by fish Pokémon, it will return to normal within a few hours.

  • Alpha Sapphire

    It apparently had a huge shell for protection in ancient times. It lives in shallow tidal pools.

  • Omega Ruby

    When its natural enemy attacks, it oozes purple fluid and escapes.

  • White 2

    Long ago, its entire back was shielded with a sturdy shell. There are traces of it left in its cells.

  • Diamond

    It has a pliable body without any bones. If any part of its body is torn off, it grows right back.
