While heading to Driftveil City Ash and co. encounter two Irate Pokémon known as Deino. As they were Dark/Dragon-type Pokémon Iris thought of them as cute, but Ash didn't think so as they were eating the lunch Cilan made for them. They also meet a young man by the name of Bobby, who runs a Pokémon day care and they learn he's watching the Deinos until their respective trainers come back. Except the third Deino because its all alone when its trainer didn't come back soon and Iris was willing to cheer Deino up. Can Ash and co. help Bobby keep the two Deino under control? Will Iris be able to cheer this lonely Deino up? And what is Team Rocket up to this time?
