So I decided to play Light version as a female named Rose. The only challenge I'm doing is the Egglocke. I first started having problems when I chose my starter Pokemon. I chose Delta Charmander. It said to swap out the Delta Charmander for a Pokemon Egg. Than it gave me this screen.
So I put Delta Charmander in the box and took it out again. I got Delta Charmander back and it was nicknamed Egg Token but I beat Damien.
