Who's that Pokémon?
It's Unnamed Turtle!
I don't get it.
Is this some pokemon we dont know of yet?
An early concept that never made it. One of the few we know about.
Search 'unreleased pokemon' on bulbapedia
It's a Ditto.
I am guessing you are promoting the existence of an unreleased Pokemon? Still, the concept of a turtle is used in one of the Generation 5 Pokemon.
Thanks for reading.
