Zill

Zill is a recurring character in the Legend of Zelda series, first appearing in The Wind Waker.

The Wind Waker
Zill is the younger son of Abe and Rose on Outset Island in The Wind Waker. This inquisitive boy lets his nose run on purpose, and follows his older brother, Joel, and Link around persistently. Interestingly, Zill's nose will continue to run even if he is in the water.

The Minish Cap
In The Minish Cap, Zill is a little kid in Hyrule Town who wishes he could go to the town school. He is often seen with two other kids, Lolly and Candy, either wandering around town, on the Royal Hyrule Library's roof, or inside the Happy Hearth Inn. If Link speaks to him twice in a row, he'll start following him around. Link can also fuse Kinstones with Zill and his friends.

Trivia

 * Zill and Joel share similarities with Malo and Talo, two brothers from Twilight Princess.
 * Zill, with his famous runny nose, is extremely similar to the Gen.5 Pokemon Cubchoo. They both have a noticeable running nose and have somewhat similar features.
