the opening, when i saw arbok in the tree, my reflex went off of thinking "UH-OH! TEAM ROCKET!"
And there were a lot of cameos of cool pokemon.
1. Ninjask in the tree before Arbok.
2. Gorebyss with all the water pokemon.
Animation was very good, i love thinking how real pokemon is. Except in the opening when they showed Haunter on the mountain path...so fake.
