Trill

Trill is a tame bird, the pet of Coro, in The Legend of Zelda: Twilight Princess. He is blue in color, with a large yellow beak, and has a hairstyle very similar to Coro's. He operates a small shop in the forest of Ordona Province, near the Forest Temple (Twilight Princess). There, he sells lantern oil and healing potions for his master, to whom he refers as "the boss."

When Link first encounters him, Trill congratulates Link on dispatching a cluster of Bokoblins (or, if he has not already done so, asks that he do something about them).

At any time, Link can purchase oil or potion by dipping an empty bottle or, in the case of the oil, his lantern into one of the vats outside of the shop Trill maintains for Coro. To pay for the items, he must deposit the correct number of Rupees into the payment box. If he attempts to shortchange the merchant, Trill will criticize him for being cheap; if he attempts to leave without paying at all, Trill will attack him. Otherwise, however, Trill is very peaceful and friendly.
