The Wubbulous World of Dr. Seuss (1996)

S1E8 Mrs. Zarbarelli's Holiday Baton

Mrs. Zabarelli had orchestrated the town’s Jingle Day Pageant for forty-nine years, but this season she passed the reins to her eager pupil, Annie DeLoo. One by one, the disgruntled cast members walked out, leaving only Annie, Horton the Elephant, and his son Morton to carry on. Now the three of them must somehow stage the entire pageant—and ensure the sun rises on Jingle Day.
