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. Much like its pre-evolved form, it has a slug-like body with a round head and a mantle covering the top half of its body. It has six stubby legs and three black eyes with white irises. A yellow stripe runs along the edge of its mantle, through its lower two eyes, and around the back of its head. Like Shellos, Gastrodon has two forms based on the sea it lives in.

In its West Sea form, it has a pair of large tentacles on its head that curve upward, as well as a smaller, straighter pair of tentacles on its neck. Its underside is pink, while its mantle is brown with three pink spots on each side. There are two lumps on its back, resembling the cerata on real-life sea slugs.

In its East Sea form, it retains the head tentacles it had as a Shellos, which are now fully green and angled slightly more upward. Its underside is blue, while its mantle is green with two blue spots on each side. It has a pair of yellow, fin-like cerata on its back and a wavy yellow line bordering its side and rear.

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. Its body is soft and squishy, yet surprisingly resilient. It has strong regenerative capabilities that allow it to recover from injures within a few hours. Its diet consists mainly of plankton, but it is occasionally known to look for food on land, leaving behind a trail of sticky slime. However, Gastrodon cannot stay on land for too long due to its body being highly vulnerable to dehydration. In ancient times, it had a shell on its back, which gradually became 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.

Brilliant Diamond It has a pliable body without any bones. If any part of its body is torn off, it grows right back.
Shining Pearl It apparently had a huge shell for protection in ancient times. It lives in shallow tidal pools.
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.

Trivia

File:Spr b 4d 423b.png
Early back sprite of Gastrodon
  • According to an interview in Nintendo Power with Ken Sugimori, Shellos and Gastrodon were originally intended for Pokémon Ruby and Sapphire, but they were ultimately not implemented due to time constraints.
  • Both Shellos and Gastrodon have early back sprites within the game data of Pokémon Diamond and Pearl; however, there are no front sprites for these forms.
  • In Diamond and Pearl, no in-game Trainer uses East Sea Gastrodon in battle, even on the east side of Mount Coronet.
  • Prior to Generation VI, Gastrodon's shape was 32px.
  • Gastrodon and its pre-evolution were accidentally released in Pokémon GO on April 29, 2019, but were removed shortly after. On May 17, 2019, they made their official debut along with various other Pokémon from Generation IV.

Origin

Gastrodon is based on a sea slug, perhaps one of the order Opisthobranchia. It may also be based on a sea hare, a type of sea slug that is also known to secrete purple fluid in self-defense.

Name origin

Gastrodon is a combination of gastropod and don (Spanish for lord). It may also derive from Gastropteron, a genus of sea slug.

Tritodon is a combination of from Tritoniidae or Triton (referring to either the common name of the gastropod genus Charonia) or the aquatic Greek god and don. It may also involve the word torito (Spanish for little bull, referring to its appearance).
