Pokédex Entries

red

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

OMASTAR uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.

emerald

An OMASTAR uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large, making its movements slow and ponderous.

firered

Its tentacles are highly developed as if they are hands and feet. As soon as it ensnares prey, it bites.

leafgreen

Despite having strong fangs and tentacles, it went extinct when its heavy shell made it unable to catch prey.
