Update [Mon 17th Apr, 2023 14:47 BST]: The Pokémon Company has now shared details of the "newly discovered Pokémon", which will be making its debut in The Hidden Treasures of Area Zero DLC.
Here are all of the details of the mysterious new turtle:
Who’s That Pokémon?!
This unknown Pokémon is reminiscent of the Legendary Pokémon Terapagos, but its name and true nature are shrouded in mystery. It is small in stature and not particularly strong, but when push comes to shove, it can crystallize the energy in its body to form a protective shield. Apparently, it can also assume a dormant state when it feels that its life is in danger by pulling its head, limbs, and tail into its shell and making itself look like a jewel.
In The Hidden Treasure of Area Zero, players will leave the Paldea region and be able to delve deeper into the world of Pokémon Scarlet and Pokémon Violet
