I would love to get a Thudurus I have been looking for some Dream World Females I have and I have a few. Let me know if you would like any of the following: Torkoal, Phanpy, Houndour, Kangaskhan.
Also, since you seem to be collecting Dream World Pokémon, I was wondering if you would happen to have a Dream World Riolu?
Thundurus is one of those I just simply clone and pass along. I had to seek a Thundurus myself to get Landorus, and I now have the new formes of them on White 2 thanks to Dream Radar. If you'd like, I can send a clone of the one from my Black game and I won't even ask for anything (though if you have any special babies you've been busy breeding, or any DWFs, I am definitely interested).
