Use the Iron Stock to craft 4 Horseshoes, then apply the Horseshoes to Baby at the Darkmoon Faire.
You may have seen my horse, Baby, over near the wagons. She pulls the cart that hauls some of the animals in our Zoo Bizarre.
She's a hard worker and she tears through shoes like you wouldn't believe. It's about time for a new set. I've already bought the raw materials.
All you need to do is shape them over an anvil and apply them to Baby's feet. It's a quick job and worth some tickets, wouldn't you say?
