The Bucket-o-poop is a craftable item from the Reign of Giants DLC. It is crafted using 4 Logs, 2 Bone Shards and 3 Manure. It is used to maximize the uses of Manure as fertilizer. It has ten uses, each use decreasing its durability by 10%.
Despite Manure being able to be used as fuel, the Bucket-o-poop is unable to fuel fires. It can however still extinguish smoldering objects.
