there is a wesite called howrse helper and there is a link at the top called objectives click on that and it takes you through all the objectives and how to do them :-)
What is the objective
You breed a unicorn. Period.
an apple someone sends to you for an objective
you have to congratulate someone on there birthday :)
100 droppings
Howrse has a page for people's birthdays. Click on one of them and then you click congratulate.
You just have to get more money by selling things or doing other things. Go to the shop and click on the resell objects button and you can sell manure and other things you don't need.
When you get to the objective that tells you to name your horse "Tip", then you will get a prize for completing the objective.
You have to find a foal game schedule. If you are on International Howrse, there is one in Dr. Zig's forum.
It doesn't mean anything really. It's just an objective Howrse makes you do.
Profile > my account > invite friends From this page you can enter the email address of a friend and invite them to sign up to the Howrse game. If they complete registration then you pass this objective.
To complete objective 20 you click your horses name and click rename then you call it Tip.
