Somewhere in the dark and nasty regions where nobody goes, stands an old and spooky castle-home of the Bad Tempered Thing. In the dark lower regions of the castle, Berk grudgingly slaves away carrying out the orders of the Thing. To win his ultimate reward - a safe full of loot - Berk has to complete up to five bizarre tasks (four in Learner mode) quickly and accurately before the Thing's anger boils over. Each task is completed when Berk sends his offering Upstairs on the dumb waiter and the Thing accepts it.
