Pokédex entries

Red
Blue
Its hard shell repels any kind of attack. It is vulnerable only when its shell is open.
Yellow The shell can withstand any attack. However, when it is open, the tender body is exposed.
Gold It swims facing backward by opening and closing its two-piece shell. It is surprisingly fast.
Silver Grains of sand trapped in its shells mix with its body fluids to form beautiful pearls.
Crystal Clamping on to an opponent reveals its vulnerable parts, so it uses this move only as a last resort.
Ruby
Sapphire
At night, this POKéMON uses its broad tongue to burrow a hole in the seafloor sand and then sleep in it. While it is sleeping, SHELLDER closes its shell, but leaves its tongue hanging out.
FireRed It is encased in a shell that is harder than diamond. Inside, however, it is surprisingly tender.
LeafGreen Its hard shell repels any kind of attack. It is vulnerable only when its shell is open.
Emerald At night, it burrows a hole in the seafloor with its broad tongue to make a place to sleep. While asleep, it closes its shell, but leaves its tongue hanging out.
Diamond
Pearl
Platinum
It swims backward by opening and closing its two shells. Its large tongue is always kept hanging out.
HeartGold It swims facing backward by opening and closing its two-piece shell. It is surprisingly fast.

At night, this Pokémon uses its broad tongue to burrow a hole in the seafloor sand and then sleep in it. While it is sleeping, Shellder closes its shell, but leaves its tongue hanging out.
Sun The hardness of its shell surpasses the hardness of a diamond. In days gone by, people used the shells to make shields.
Moon This Pokémon’s tongue is always hanging out. It uses its tongue with great dexterity to dig up sand from the seabed in its search for food.
Ultra Sun The sand that accumulates inside its shell eventually becomes a pearl. But the pearl gets in the way, so it spits it out and discards it.
Ultra Moon Even when its shell is closed, its tongue still hangs out. If you give its tongue a good yank, the shock will cause Shellder to open its shell.

Let's Go Eevee
The shell can withstand any attack. However, when it is open, the tender body is exposed.
