Pokédex entries by game

Descriptions recorded in these games. This list does not establish where the Pokémon can be caught or transferred.

Diamond

Its colors and shapes differ from region to region. In the Sinnoh region, two types are confirmed.

Pearl

It lives along bodies of water. Its body shape has changed to suit its habitat.

Platinum · Black · White · Black 2 · White 2 · X · Omega Ruby

Beware of pushing strongly on its squishy body, as it makes a mysterious purple fluid ooze out.

Heartgold · Soulsilver · Y · Alpha Sapphire

Its shape and coloration vary, depending on its habitat.

Sun

For the most part, it makes its home along the seashore. Its color and form differ according to its habitat and the quality of its food.

Moon

Purple mucus sticks to the hands of anyone who touches it. Take care, as the substance is troublesome to wash off.

Ultra Sun

While they normally live in the sea, they can function on land, too, until their skin dries out.

Ultra Moon

When it senses danger, a purple liquid oozes out of it. The liquid is thought to be something like greasy sweat.

Sword

This Pokémon’s habitat shapes its physique. According to some theories, life in warm ocean waters causes this variation to develop.

Shield

Subjecting this Pokémon to a strong force causes it to secrete a strange purple fluid. Though harmless, the fluid is awfully sticky.

Legends Arceus

Found in abundance on seashores bordering warm waters. Shellos are unexpectedly friendly and will crawl toward any person they see. Take care not to get coated in mucus!
