Hardy gout tubers

Hardy gout tubers are obtained during the My Arm's Big Adventure quest from Murcaily. They can not be dug up or planted in a herb patch. One hardy gout tuber is given to the player after reaching 60% favour in Tai-Bwo Wannai Cleanup, but then Murcaily gives the player a handful of them after My Arm goes on a rampage.

They have no real use, except to be given to My Arm at the near-end of the quest, before the final fight with Giant Roc and Baby Roc.
