The Skullball Boss oversees the Werewolf Agility Course. He will teach players how to use the Werewolf Skullball course properly. This course requires a ring of charos and completion of Creature of Fenkenstrain. If you want to start a game of Skullball, you'll have to talk with him and a skull, which acts as a ball, will appear.
What you do as you play the Skullball game, is you tap, kick, shoot or show-goal. If you click one of these, your character will kick the Skullball from which ever side he is facing it. Tap will kick the ball one (1) step. Kick will kick the ball five (5) steps. Shoot will kick the ball 10 steps. Show-goal will get the yellow arrow and point it to where you have to kick the Skullball to. The faster you finish the loop, the more Agility experience you'll get.
