One time, Tracey was saying how well Marill and Venonat work as a team, and Misty says "At least they're not Bug types.". How did she become a Gym Leader if she doesn't know that? XD
Apparently, Arbok was told to use Poison Needle, which is the Japanese name for Poison Sting. Never mind just leaving the Japanese Pokémon animé cries in the animé, they actually leave the move names as well.
The Arbok ---> Seviper evolution mistake really confused me. It was when I was new to Pokémon, and even then I knew that Arbok didn't evolve into Seviper.
Wow, the dub really messes up simple facts about Arbok, doesn't it?
