Gastrodon

Diamond It has a pliable body without any bones. If any part of its body is torn off, it grows right back.
Pearl It apparently had a huge shell for protection in ancient times. It lives in shallow tidal pools.
Platinum Long ago, its entire back was shielded with a sturdy shell. There are traces of it left in its cells.

Shining Pearl It apparently had a huge shell for protection in ancient times. It lives in shallow tidal pools.
Legends: Arceus Eats beach sand for nourishment. Should one Gastrodon encounter another of a different color, a fierce battle will inevitably ensue.

West Sea Form

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.
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.
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.
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.
Sword Its search for food sometimes leads it onto land, where it leaves behind a sticky trail of slime as it passes through.
Shield The softness of its body helps disperse the force of impacts, so although its body is uncommonly squishy, it’s also surprisingly resilient.

East Sea Form

Sun A team of researchers is scouring the oceans of the world in search of a Gastrodon in a color never seen before.
Moon Experiments are being conducted to discover what happens when a Gastrodon is raised in a location other than the sea where it was born.
Ultra Sun When it’s attacked, it gushes a purple liquid that’s not poisonous but makes Gastrodon’s meat bitter and inedible.
Ultra Moon A relative of Shellder and Cloyster, this ocean dweller sometimes comes onto land in search of food.
Sword It secretes a purple fluid to deter enemies. This fluid isn’t poisonous—instead, it’s super sticky, and once it sticks, it’s very hard to unstick.
Shield Its body is covered in a sticky slime. It’s very susceptible to dehydration, so it can’t spend too much time on land.

East Sea

Legends: Arceus Found more often on the land than in the sea. More active when it’s cloudy or rainy out than when the weather is fair.
Scarlet They normally inhabit rocky seashores, but in times of continuous rain, they can sometimes be found in the mountains, far from the sea.
Violet Fishers say that they didn’t see many of these Pokémon in the past, but this form of Gastrodon is now increasing in number.

West Sea

Scarlet Its whole body is sticky with mucus. In the past, this form of Gastrodon was by far the more numerous one.
Violet It appears on beaches where the waters are shallow. Once it catches prey, it will slowly melt them with its mucus before slurping them up.
