I loved this episode. Bianca is a great character and I loved how she was obsessed about keeping things dirty and how Iris kept getting mad at her. I think she and Ash could have a good friendship/rivalry going on there.
They made Bianca annoying in a good way. How is that even possible?! I thought her dub voice was pretty good, by the way. Lol'd pretty hard when Minccino used Attract on Snivy.
