This was a really weird episode, and not just because of Kojirou's tig ol' bitties. The whole thing - the kids befriending a creepy old pedophile, the unusually (for this show) realistic portrayal of women in bathing suits, the nonsensical plot - feels like a random, throw-away fanservice-y episode instead of the logical progression from a three-episode arc to Satoshi's next Gym Battle. When I watch this episode, I get the same feeling I would get if someone took a volume of Pokemon Special and then crammed an uncensored Dengeki Pikachu
chapter into the middle of it. Really weird and out-of-place.
