Picto Box Thief

The Picto Box Thief is a character from from The Legend of Zelda: The Wind Waker. As his name implies, he is a thief who stole a Picto Box. When Link first comes to Windfall Island he discovers Tingle locked in the Town Jail. After freeing him, Link continues to investigate the jail and discovers the Picto Box. According to a message left behind by the thief, he had desired the Picto Box for a long time and eventually stole it. He was caught however and imprisoned in the jail. He managed to prevent the Picto Box from being taken from him and set to escape the jail via tunnelling out. According to Lenzo the Picto Box was stolen from him suddenly a long time ago when he rented a room beside a traveller for a single night.

Aside from his brief history, the Picto Box Thief also left behind instructions on how to use the Picto Box.

Tingle is the Thief
The fact that Tingle is arrested and imprisoned suggests that he stole the camera and was doing time for his crime before Link freed him. However the message Link reads from the Picto Box Thief states he plans to escape by tunnelling out and the villagers of Windfall refer to the event as happening quite some time ago where's Tingle's visit and incarceration seem much more reason. Tingle himself alongside Zunari also state Tingle was incarcerated for his suspicious appearance.

The Thief Is Dead
In the same room where the Picto Box and the Tief's message is found, Link can also find a set of bones including a skull. It is possible this skull belongs to the original owner of the Picto Box meaning he perished without ever escaping the Windfall Jail.
