Pretty flower

Pretty Flower is the name of a quest item and troll warlord in the quest "King of the Dwarves"

In order to continue the quest, you must give a pretty flower(item) from My Arm to Pretty Flower(NPC).

After the quest, you can get another non-wiledable "pretty flower" from My Arm, and present it again to Pretty Flower or to his son Sparkly Crystal, but this appears to be just for humor.
