Tran'rek in Gadgetzan wants you to kill 8 Gnarled Thistleshrubs and 8 Thistleshrub Rootshapers.
Gnarled Thistleshrub: 0/8
Thistleshrub Rootshaper: 0/8
Have you ever seen Thistleshrub Valley? It's a mighty dangerous place, <name>.
Those strange beasts there, I don't trust them for a minute! Gnarled thistleshrubs and thistleshrub rootshapers, that's what I think they were called...
Anyhow, I want to get into the valley, but with so many of those thistleshrubs around, there's no way I'm going back there. But here's where you come in -- if you clear some of them out, I just might think about going back. What do you think, <name>? Help me out?
