Gastrodon (Japanese: トリトドン Tritodon) is a dual-type Water/Ground Pokémon introduced in Generation IV.

It evolves from Shellos starting at level 30.

Gastrodon have two different appearances: West Sea (pink and brown) and East Sea (blue and green), found on the respective sides of Sinnoh's mountain range.

Biology

Gastrodon is a sea slug-like Pokémon and appears much the same as its pre-evolution, but it gains four more stubby legs and is noticeably larger. They both have plain black eyes with white irises, with a third eye in the center of their forehead. Like Shellos, Gastrodon has two forms which is influenced by its diet and the sea it lives in.

In its West Sea form, the flower-like crest it had as a Shellos has now turned into horns adorning the side of its head, which point directly upwards in a crescent moon shape. Its underside up to the bottom of its mouth is pink, its back and the top of its head is completely brown, and it has two small protrusions on its back with several pink spots dotted around them. It also has two small protrusions on its neck underneath the horns, and it has a yellow border running down its body from its head, separating the brown and the pink coloration.

In its East Sea form, it retains the horns it had as a Shellos, although now fully colored green which point at a 45-degree angle. Its underside up to the bottom of its mouth is blue, its back and the top of its head is completely green, and it has two yellow "fins" adorned on its back with a third bordering its side and rear, as well as two small blue spots between them. It has a yellow border running down its body from its head, separating the blue and the green coloration.

Gastrodon and its pre-evolution Shellos are examples of allopatric speciation, though they are still able to breed. It is also a relative of Shellder and Cloyster. When it is threatened, it oozes purple fluid and flees. Gastrodon lives in shallow tidal pools. Gastrodon has strong regenerative capabilities that allow it to recover from injures within a few hours. Gastrodon's main diet consists of plankton. However, it is known occasionally looks for food on land leaving a sticky trail of slime in the process. It is known to have a surprisingly resilient body despite its soft and squishy appearance. Gastrodon cannot stay on land for too long due to its body being highly vulnerable to dehydration. In ancient times, it used to have a shell on its back which has changed into a thin yet hard vestigial plate.

East Sea
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.
West Sea
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.
Generation VIII Galar
#231
East Sea
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.
West Sea
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.
