The Tingle Bottle is an item from the HD re-release of The Legend of Zelda: The Wind Waker. Replacing the Tingle Tuner, it is given to Link in Windfall Island's Town Jail by Tingle once Link frees him from his cell. Its function is to post messages and pictures Link has taken with his Picto Box to Miiverse.
Link can find bottles throughout the Great Sea that other players have sent and view the messages or pictures inside. This function can be used to give other players hints or photos for the Nintendo Gallery, as pictures can be taken from other posts.
