leafeon is adorable. :3 i didn't get a leafeon until really late in the game, though, so i never got around to training it. I wish i had a leafeon and a glaceon in my party, because then i would have all the eevelutions in my party except umbreon (nothing against umbreon, it's just that there's only room for six.) Right now my party (in diamond) consists of:
vaporeon
jolteon
flareon
espeon
dodrio
all in the higher 70s levels wise
