Planet Minigolf

All you have to do is just win a round of mini-golf on the Stronghold Island "Extreme" Course. After you finish the 9th hole and are in first place, the trophy will pop! An extremely easy way to make sure you get the lowest score possible on each hole is to play through it and if it looks like you are going to get a higher score than you want, pause the game and select "Restart Hole". It will not effect your overall score, but will take you back to the beginning of that hole and reset your score for it (so you get another shot at it). You can do that as many times as you need until you get a score you are happy with on it! Also you can check out this thread for helpful tips on the different holes!
