Having just watched this episode I can say that I'm sorry 4kids skipped it, it actually was a very good filler.
I have to say, Brock thinking he was holding Joy's hand and trying to kiss Joy while laying in bed only to find out that it was Jynx instead was one of the funniest moments of the pokemon anime.
Surprised that Swinub and Piloswine were in this episode. Also, WTF continuity?! There was a picture on the wall of the Pokemon Center that showed the tan Nurse Joy from the Orange Islands, the one from "The Joy of Pokemon" that went on her little boat going from island to island treating Pokemon. WTF? Can anyone who can understand Japanese explain what Joy said when talking about the tan Nurse Joy in the picture?
Nice to see Brock stand his ground against Team Rocket. Man that was brutal, Arbok completely dominated Brock and Geodude. I didn't expect Arbok to wrap his tail around Brock and continually slam him to the ground. Also TR using some heat machines to faint Jynx, Piloswine and the Swinub was pretty unique.
Also yay for Misty actually battling! The damn girl wouldn't let go of Togepi in the entire episode though, even when she had a blanket over herself. Sheesh, it was almost like Togepi was permanantly stuck in her arms. Bah.
Anyway this was a really nice filler, I liked it a lot more than I expected to. Shame it was never dubbed.
