I found this slightly entertaning. Also you saw how close Ash was to Dawn? I bet he enjoyed that and though "Alright Pikachu, just keep it up... yeah..." I'm serious, I hope I wasn't the only one who noticed that.
But... did it have to be same gender Pokemon? Little children do not enjoy that and you know how epic this would have been if it had been Pikachu and Buneary? This was a great idea for an episode but the same gender bit kind of killed it all. >_<
Also... Brock was too knowledgeable. We need more flirting, less smartness, and of course, less buttrape from him. I bet Croagunk enjoys that anyways.
Why can't they be the same gender?
I don't see anything wrong... Just a bit random, I've only seen the preview in Japanese and it looks so random but nothing else is wrong.
