Back at the Barnyard (2007)

Season 1: Episode 16

When Duke tries crazy methods for the sheep to be safe during bear season, they escape and now Otis and Duke must go on a cross country trip to get them before they escape to New Zealand. Meanwhile, Abby and Bessy dress Pig, Freddy, and Peck as sheep. But it backfired when the farmer thought Pig had the "nervous woolies" when Pig accidentally said "Beeeee" and "Boooo" instead of "Baaaa".
