I can't find your Timburr on the GTS... Are you sure you typed in "Nidoran" (you will need to go into the special characters to get the symbol, otherwise it won't show up on the GTS when I search for your Timburr).
You have a cart with OT: Chicken right? If the scrap didn't originate from your game it won't give your TSV but the originator of OT: Chicken's TSV.
OT: Chicken's TSV is: 0170 (if that's one of your carts)
Hey I'm currently in a trade...
It won't really take long, but I'm going to need about four minutes to complete the trade and get my Pokemon, so if you want to look for another battle it's alright :)
Otherwise, I'll be on wifi shortly
