This Cloyster is a water/ice-type Pokémon owned by Giovanni.



Cloyster frozen the two Magmar's.

After Red said goodbye to Giovanni, without knowing his identity, two Magmar jumped out from behind him. He sent out Cloyster, who froze the two of them.[1]

When Poli was frozen, Cloyster stood behind Red. Giovanni explained that the time it took for Red to send out Poli and for him to attack, he froze Poli, He returned it offscreen, so they could have a bet to see who can beat the other the quickest.[2]

Known moves
