Pokédex entries

Red
Blue
A prehistoric POKéMON that died out when its heavy shell made it impossible to catch prey.
Yellow Sharp beaks ring its mouth. Its shell was too big for it to move freely, so it became extinct.
Gold Apparently, it cracked SHELLDER’s shell with its sharp fangs and sucked out the insides.
Silver Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs.
Crystal Its heavy shell allowed it to reach only nearby food. This could be the reason it is extinct.
Ruby
Sapphire
