 Wallace is unable to sleep after eating too much cheese, so he activates his Snoozatron to remedy the problem.The device wakes up Gromit, who puts on a sheep costume and heads downstairs; meanwhile, robotic arms fluff Wallace's mattress and pillow, place a hot water bottle on his chest, and give him a teddy bear as a record of lullaby music starts to play.After Gromit reaches the dining room, a huge spring built into the floor repeatedly bounces him upward, through a trap door in the ceiling, and into Wallace's bedroom.
