Unlike other Zelda games (where you got attacked if you hit the Cuccos), in Twilight Princess if you hit a Cucco about 8 times, you'll be able to control it for a short period of time.

If you visit the Fishing Hole in Upper Zora's River, there's a mini game Hena will let you play for 5 Rupees called Rollgoal. If you make it past 1-8, you'll be rewarded with the Frog Lure. However, if you keep going and beat the entire thing, up to and including 8-8, you'll be able to play the special-edition version of Rollgoal. You can choose any level, the cost is free, the time limit is raised to 4:00:00, and you cannot win any Rupees. Also, as an added bonus, once you beat 8-8, Hena will fill your wallet completely!
