Beaver Race

Beaver Falls Race is a racing minigame featured in Majora's Mask.

Location
To begin the minigame, Link must go to the Waterfall Rapids in Zora Cape. Once there, he has to take Zora form and talk to the beaver swimming around in the water. After a brief exchange, he challenges Link to compete against him, which leads to the first of two races that must be completed successfully in order to obtain the grand prize - an empty bottle).

Rules
The first race against the Little Brother consists of swimming through 20 underwater rings in under two minutes. Upon succeeding, Link will now have to race against the Big Brother, but this time there are 25 rings. Successfully completing both races leads to a reward of an empty bottle. Racing again against the beavers during the same three-day-cycle yields an opportunity to win a Piece of Heart from them. The rules for the first race are the same, except the time limit has been shortened to one minute and 50 seconds (a ten-second difference). Once Link wins against the Little Brother, he'll have to race against the Big Brother with the same time limit, but with 25 rings instead. The Piece of Heart is rewarded upon the completion of the two races.

Originally, the minigame was to collect sticks to help build the dam; however, Nintendo ultimately opted against it.
