Trockbladder was a sport played by Woodtrolls in the Deepwoods, similar to basketball. The ball was made from the bladder of a hammelhorn, stuffed with Trock Beans. There was only one basket, and both teams tried to score in it. A player with the trockbladder counted each step he or she made, and could choose to either pass the ball to a teammate, try to reach twelve steps, or attempt to score a basket. If a player made a basket, the corresponding team gained an amount of points equal to the number of steps the player reached. If the maximum number of twelve steps was reached when a goal was scored, the value of the shot was doubled for a score of twenty-four points.
