Trill's Shop

Trill's Shop is a location in Twilight Princess situated in North Faron Woods right before the Forest Temple. It is a small shop owned by the bird Trill that offers Red Potion and Lantern Oil only. After scooping the necessary refills in a bottle, Link must make the payments near Trill in a box he provides. If Link leaves without paying, he'll label Link as a "thief" and peck him every time he enters his store. The bird will stop pecking Link when he finally pays for what he took.

Trivia
It's possible to steal from Trill's shop without the bird noticing. If the player saves and exits the game after Link takes the items, Link will be at the entrance of North Faron Woods, with the items in his possession.
