An all-night gaming session turns the Farmer and Bitzer into sleep-deprived zombies the next day. Shaun takes the chance to change Bitzer's checklist to suit himself, but he manages to miss the final item: shearing time! 

Bitzer is embarrassed when his dad makes a surprise visit and finds the farmyard in a mess. Feeling sorry for Bitzer, Shaun and the flock make a real show of tidying up. Bitzer and his dad get some bonding time, but as soon as dad leaves, the place descends into anarchy once more.
