Shaun the Sheep and the whole flock from Mossy Bottom are back, and an adventure awaits them that’s sure to make their wool stand on end! Following a visit from outer space in Farmageddon, an even bigger challenge is looming – they must catch the hairiest beast in the neighbourhood and save Halloween. Everyone at Mossy Bottom Farm is looking forward to Halloween… But the clumsy farmer destroys the much-loved pumpkin patch, and the celebrations are over! So Shaun takes matters into his own hands – he transforms himself into a mad scientist and tries to put everything right. But as is often the case, the plan goes awry faster than you can say ‘baaa!’ The farmer vanishes, a mysterious monster is on the rampage in the woods, and Mossy Bottom turns into an epicentre of chaos. Shaun and the whole flock must therefore embark on an action-packed quest full of crazy ideas, unexpected twists and loads of fun.
