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.
