Clifford the Big Red Dog on PBS

An hourlong Valentine's Day show features four stories. In the first, Cleo makes a “gigantic Valentine surprise” for Clifford and T-Bone, and wants an equally big surprise in return. Then, Emily Elizabeth writes a fan letter to her favorite pop star (and gets something big in return); T-Bone's baby-sitting duties tie him down when the love of his life, Mimi, visits; and Charley gets carried away (and neglects his duties) when a magic craze sweeps Birdwell.
