I have tried for the Harvest Horn many, many times to no avil. I've even used gems. I'm seriously beginning to think the game knows when ppl use gems and hold out on giving us the animal we want so we'll keep buying gems. I don't want to think that, but I don't know what else to think. I've used so many gems to get this one bcos I really like it. I may just give up on it which saddens me greatly.
