Pokedex descriptions

Red Blue LeafGreen	When attacked, it launches its horns in quick volleys. Its innards have never been seen.
Yellow	For protection, it uses its harderthan-diamonds shell. It also shoots spikes from the shell.
Gold HeartGold	Once it slams its shell shut, it is impossible to open, even by those with superior strength.
Silver SoulSilver	CLOYSTER that live in seas with harsh tidal currents grow large, sharp spikes on their shells.
Crystal	Even a missile can’t break the spikes it uses to stab opponents. They’re even harder than its shell.
Ruby Sapphire	CLOYSTER is capable of swimming in the sea. It does so by swallowing water, then jetting it out toward the rear. This POKéMON shoots spikes from its shell using the same system.
Emerald	It swims in the sea by swallowing water, then jetting it out toward the rear. The CLOYSTER shoots spikes from its shell using the same system.
FireRed	Its shell is extremely hard. It cannot be shattered, even with a bomb. The shell opens only when it is attacking.
Diamond Pearl Platinum Black White Black 2 White 2	It fights by keeping its shell tightly shut for protection and by shooting spikes to repel foes.
