The Plank is an item in Granny. It is required to escape the house. The player needs a Hammer to take it down. It can be put across the Attic hole so the Player can walk across it. A Plank falling on the floor makes a noise that alerts Granny. Three Planks block the entrance to the Baby Room and at least one of them needs to be knocked down by the Hammer to get there. It does not spawn anywhere else.
- If the Player throws an item across the hole in the Attic and hides in the chest or vent, Granny will knock down the planks and will later leave. It is unknown if this is a glitch or intentional.
- Attempting to use any other item to pave a path across the hole will result in the Player remarking "Maybe I can use one of the planks".
- It is so large, it sometimes may glitch through the Attic floor and end up on the stairs or the Main Room
- The Plank is the second item in the game that has multiple clones of itself.
