Oh man, I laughed so hard at the end, when they found that sign that said "do not enter... it is Ursaring mating season. During mating season, attacks increase dramatically." Or whatever it was. Oh god, that was rich XD
I also loved how they shuffled the groups - Ash Brock and Jessie, James Meowth and Misty. I felt bad for Misty when James and Meowth were drooling over her sandwich, lol. I felt worse for Ash & Brock being yelled at by Jessie. This was a fun filler, definitely one of the most memorable of Johto.
