WHOAH! WAIT!! [Confusion to the max here!] ...Growlithe can't learn Arcanine's Special thing - Extreme Speed. So if you want Extreme Speed, you have to evolve it, then Arcanine can learn it. And Arcanine can't learn Heat Wave, so if you want the Wave, you probably won't get the Speed.

Oh, I'm Tooyama Kintarou! Nice to meet you, nice to meet you!
