Quite probably ranks amongst my top ten of all pokemon episodes, this one had an interesting plot, featured a lot of pokemon doing non-battle things. I loved Magikarp & how proud James was of it. The best was when Gyrados showed up & James says "I'm James, your master. Obey me", moments after claiming he no longer wanted to be magikarp's master. xD
Correct me if I am wrong, but TR doesn't say the full motto in this episode, right? Then my theory of 'episodes with differences/interuptions in the TR motto being better than ones with full motto' is partially true.
"School of Hard Knocks" & "Dig Those Diglett" come to mind.
