[Crouching Carrot, Hidden Turnip] is straight broken, I throw a turnip, they say “ooh turnip” proceed to eat it… No credit. Stuck at 6/12.
You might be throwing a new one too soon. You can only have one active at a time. Once you see credit pop up, you’re good to throw another.
Side note about this quest: It absolutely amazes me how many people will run through and wipe out every varmint in the hole, and get annoyed when they can’t complete the quest. I guess Blizzard has successfully made us all hammers, and all the quest mobs nails.
