The premise behind Pippa Funnell: Stable Adventure for GBA is that your aunt and uncle have gone on a round the world trip and left you to take care of their stables. They feel they can trust you with this task as you have spent many, many hours with the horses. Every holiday and anytime you had a free day, you would spend it on the farm, generally helping out with chores and enjoying the peaceful atmosphere of the stables.
Now it's all yours for a while. Before their departure for the jungles of South America, your aunt and uncle left some money for you, just so you get off to a steady start in your new life. On your first day, you'll spend some time walking around the grounds for which you will be held responsible. This is your chance to take stock of the situation first-hand, and unfortunately the place isn't looking too good: the feed hopper is almost empty and the saddles and harnesses have seen better days. You also now have a small barn where the farm offices are located, a meadow and a stable, where a young mare awaits your attention.
So with a little renovation and repair, and a little help from your mare (plus a bit of luck) you might even be able to set up your own breeding farm. What lies ahead in your Stable Adventure?
