Pokédex entries

Shellos

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	Beware of pushing strongly on its squishy body, as it makes a mysterious purple fluid ooze out.
HeartGold SoulSilver	Its shape and coloration vary, depending on its habitat.
Black White Black 2 White 2	Beware of pushing strongly on its squishy body, as it makes a mysterious purple fluid ooze out.
X Omega Ruby	Beware of pushing strongly on its squishy body, as it makes a mysterious purple fluid ooze out.
Y Alpha Sapphire	Its shape and coloration vary, depending on its habitat.

East Sea Form

Sun	Shellos lives in the sea and feasts on plankton. The lovelier the ocean where Shellos resides, the more vibrant its color becomes.
Moon	The difference in color from one Shellos to another seems to be a result of their diet. No large changes can be seen in their capabilities.
Ultra Sun	When it senses danger, it gushes a purple liquid. Some theories suggest this liquid is a greasy sweat induced by stress.
Ultra Moon	Scientists interested in its great regenerative capabilities are currently analyzing the materials from which its cells are made.
Sword	There’s speculation that its appearance is determined by what it eats, but the truth remains elusive.
Shield	Its appearance changes depending on the environment. One theory suggests that living in cold seas causes Shellos to take on this form.

West Sea Form

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.
