Baranek Shaun Sezon 2 Odcinek 18: Cat Got Your Brain?

Two bungling alien scientists transport Pidsley and Shaun aboard their flying saucer. Unfortunately, a foolish error causes the aliens to swap the animal’s brains around. Shaun and Pidsley are dumped back to Earth, not realising they are in the wrong bodies – leading to much confusion around the farm before the aliens return to correct their mistake.
