They may only be attained during the Tai Bwo Wannai Cleanup minigame, or by purchasing one from another player. Players can also get one after clearing/harvesting herb patches if they have purchased the scroll of life from the Daemonheim Rewards shop, although this is random. Sometimes after hacking down jungle during the minigame, players will receive a message: "You hack away the remaining bush to reveal an unusual plant." The unusual plant only has an examine option, which reads: "Many plants such as this usually have exotic tubers." Using a spade on the plant gives the player a tuber. The spade from the tool belt will work.
