Timmy Drawing/ko

Timmy Drawings are in part decorative and in part lore items that was added in updated v0.20, v0.36, v0.51 of The Forest.

Gameplay
Timmy's drawings can be found in caves and in various parts of the peninsula. They show that Timmy is still alive after he is carried away by the red man. The drawings depict Timmy's encounters with cannibals and his surroundings. They are mirrored by Megan with her drawings.

Theory
It is rather bizarre that Timmy Drawings can be found in several caves, as it would not make sense for the Red Man to take Timmy to all of them, especially considering they don't connect properly. This can be explained by a number of theories. One drawing seems to indicate that while Timmy is afraid of the cannibals, he is not afraid of the Red Man. This is evidenced by a) the drawing featuring a cannibal holding a head, and b) a drawing featuring Timmy holding hands with a man drawn all in red (while another drawing shows Timmy with his father in blue with an axe, indicating the red stick figure is not dad).
 * 1) The cannibals brought the drawings and dropped them in random places in the caves, like they do for other random articles.
 * 2) The developers have stated all of the caves are connected, so perhaps the Red Man took Timmy through those hidden passages, with Timmy leaving drawings randomly, on their way to the bottom of the Sinkhole to access the vault door.

Locations
There is reportedly 11 drawings in the game. 9 are listed here. 4 and 7 are the same, as it isn't known which one they are.
