Bubda was a hermit troll that lived in a magical knapsack. He preferred rotten food and loved Yahtzee. He played this game with Seth when he was smuggling himself to Wyrmroost, and then many times with Warren when he was wounded, and when he was trapped in the knapsack. Warren developed an attachment to Bubda, and wanted him to leave the bag, but Bubda was to stubborn. Bubda can look like a barrel, or become like elastic.
