The Cheese Staff is a tool created with a stick and a Cheese (Item). Its primary purpose is to configure Rat commands and behavior.
Uses[]
In order to use the Cheese Staff, it must be "bound" to a rat. This is done by Right-Clicking the rat with the cheese staff in hand. Once bound to a rat, the cheese staff can then be clicked on any block.
Click on a chest or container block with the bound staff in hand to open up the Cheese Staff Menu. Here the player can mark the container as either a pick-up or drop off a container for the rat's various commands.
The Staff can also be used to set a home point for the rat. The home point is the block that the rat will wander around when set to "Wander" command.
