Logbook entry

The humble Bloatsac contributes to its ecology by producing large amounts of benevolent gases. It thrives in damp enviroments, though it can survive in most climates and terrains. The Bloatsac secretes a venemous sap over its body. Very few creatures can ingest the sap and survive, making it a useful defensive mechanism for the plant.
