I don't get that Mantine joke. Also, that tune when they're in the forest sounds like the Agate Village theme, and the little village in it, resembles Agate too.
Fun Fact: The GS Ball was originally introduced to set up a story arc with Celebi, which got canned due to this movie. With the village, music, Dark Balls, Evil Pokemon, Celebi and a villain controlling the Evil Pokemon, I can't help but think this movie had much inspiration for Pokemon Colosseum. And I think this only the second time you used Shoop Da Whoop. You haven't used that since your review of Wily The Sparrow.
