Animal – Chester
Chester is a unique passive mob that acts like a mobile chest. Only one of these will spawn at a time and only when a play has found the Eye Bone. Chester will follow the player as long as the player has the Eye Bone in their inventory.
Up to 9 items (9 slots) can be stored in side it. This animal will only spawn after a player has an Eye Bone in their inventory.
If you no longer want him to follow you or you just want to keep him in one location for a bit. You can drop the Eye Bone and Chester will stay where the Eye Bone was dropped. This is a great tactic if you are going near aggro monsters. You want to try to keep Chester alive. If this animal dies then all items inside will be dropped on the ground and you will have to wait 7 in games days for him to respawn. Krampus cannot steal from him.
