Fiesta en la granja (S02E17)

The Farmer is throwing a fancy-dress house party for his birthday. Bitzer is entrusted with posting the invites but fools around on the way to the post box and loses them all! Shaun saves the day again – disguised in their own ingenious costumes, the sheep stand in as the guests and have a right old knees-up. But can they fool the Farmer into believing he is surrounded by his friends? (iTunes)
