Dunsparce. It's in one of my boxes. I wanted an Adamant one, but I couldn't get one and continued playing. The first Pokémon I caught that was added to my team was a Nidoran♂, then Misdreavus, Tangela, Dratini and finally Chansey.
Hoothoot and Sentret aren't registered in my Pokédex yet and I have already beat the E4 twice! I'll have to catch them sooner or later!
