Realistic Clamperl

So i decided to start making realistic pokemon again.
This is a clamperl, i realized that clamperl is really an oyster. I did a lot of research on this and now i know how a pearl is really made.
It has to do with bactiria getting into the oysters system, that bactiria creates the pearl, it takes 5-6 years for it to be complete. with this i was thinking that that bactiria created a pearl that was alive and took over the host oyster killing it. The dead oysters insides are then eaten away, leaving just the pearl. An anemone then takes the place of the inside shell protecting the pearl. Small pokemon sometimes wander into the anemone were they're then trapped inside the shell and eaten by the pearl.

If you would like to request a pokemon, feel free to either note me or leave it in the comments below.
