Beaver Race

Once you enter Zora cape turn left past the jar destroying game you'll notice the ledges and palm trees, work your way up to the top to find Beaver falls.

Once there, you should talk to the beaver as zora Link and race him. Swim through all 20 rings before the time runs out and his big brother shows up and challenges you to another race, but this time you must pass through 25 rings! If you complete this challenge, you'll receive an empty bottle. If you do the whole thing over again on the same cycle of days, you'll have to do the races in ten seconds less, You'll get a piece of heart the second time around.
