I don't think so. There's no other pokemon in the 'Water 1' or 'Dragon' egg-groups that learns Extremespeed, so who would you breed it with? --- "I think all you gotta do is find that little black kid, and doesn't that start the whole backdoor option?" -WHiTE_LickR
After you finish the 8th gym in HG/SS you have to go to the dragons den, answer a few questions and then leave.
However, if you answer the questions "correctly" you will be given a level 15 dratini with xtreme speed, but youll have to go back in once you have come out. Save before you talk to the old geezer again and you can get desired nature to. --- XBL GT - Ben 3069
No can do...unless you get the ES Dratini from the Dragon's Den in HG/SS. --- My great weakness is the love I have for the fair sex, and pretty much all my trouble comes from or can be traced to that charming source. - Myles Keogh
I think not everybody get it. If you are at the 8th gym in heartgold/soulsilver. You must do a few things in dragon's den. Then you need to exit the cave. And go back inside. After this you need to answer a few questions and then you get a dratini. If you answered the questions correct then you get a dratini with extremespeed.
But you can only get 1 in the game. But if you breed it. Then can you give/trade it with me ;) I don't need some with good nature, ... because I'm gonna breed it by myself.
PS: I didn't have heartgold/soulsilver (that's the reason I'm asking for it) But I played on crystal a long time ago. And I remembered I get one with extremespeed.
