“Back at the Barnyard” (9 p.m., Nickelodeon): Get this party started with the party

“Back at the Barnyard” (9 p.m., Nickelodeon): Get this party started with the party animals who populate “Back at the Barnyard,” a new CGI-animated series on Nickelodeon. Based on last year’s feature, “Barnyard,” the series takes place at a farm where animals make merry whenever the farmer’s back is turned. At the center of the shenanigans is fun-loving Otis, who’s surrounded by his best friend and fellow bovine, Bessy; Pip, a wisecracking mouse; and paranoid ferret Freddy. The show, created by Steve Oedekerk (“Jimmy Neutron: Boy Genius,” “Ace Ventura: Pet Detective”), premieres 9 p.m. Saturday. After that, it will air Saturdays at 10:30 a.m.
