Link's Crossbow Training Cheats

Scarecrows
While playing through some of the target practice levels in the game, you may see a Scarecrow. Shoot it in the chest as many times as you can when it appears, a minimum of eight times, and you will hear a bell chime. When this occurs, the head of the Scarecrow will get bigger. Shoot the head to get a quick 1,000 points.

Now, if you did this correctly, later on any given stage, a second Scarecrow will appear. Repeat the same process on this one as you did on the first one, shooting it at least eight times in the chest and then shooting its head. If you do this, when the screen changes for a third and final time on the stage you're on, a new level will appear instead of the normal third leg of the stage you're on. More points will be available here.

Platinum Medals
Platinum Medals seem nearly unobtainable in many stages throughout the game. The prime way to build up your points to "platinum levels" is to simply rack up large streaks of hits without missing. Otherwise, you will have considerable difficulty in getting Platinum Medals everywhere.
