Schalellos

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 +6: Beware of pushing strongly on its squishy body, as it makes a mysterious purple fluid ooze out.

HeartGold +3: 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!
