I loved how James was wearing a pink tutu in this episode. It seems like he crossdresses a lot during this season.
I thought that Misty made a great mermaid, she looked so pretty! Also, it was good to see more of Horsea this episode, it's so cute. Too bad Seel/Dewgong stole the spotlight from it. :/
Oh, and it doesn't make sense how Misty and Arbok could breath underwater that long.
