Right now the style/theme I have for PC on my computer is the Arceus one, and I like how it makes my theme look (although I never did anything) And it really brings out the green in yours!!
Pretty good, so far. And guess what? I was playing my Japanese version of HeartGold (I mainly played SoulSilver, so I wasn't ver far in HeartGold) and my Croconow (Gator) and Flaaffy (Bolt) evolved at the same time! I though that was kinda cool. Now I'm at the Cianwood Gym.
