New designs format.

The show's focus this season tightens in on certain, select characters:

The cast of Muppets, which has mushroomed over the decades, will be pared down to focus on a core six: Elmo, Cookie Monster, Abby Cadabby, Grover,Big Bird and Oscar. The others will still be on the show, but the core cast will be the daily focus.

The season also marks the show's move to a new channel. The episodes will debut first-run on HBO and will air on PBS following a nine-month window. The season also introduces a shortened, half-hour format, completely dropping the hour-long run time.

Episodes include Elmo and Abby posing as "Boo-Boo Busters," a special Mothers Day episode and an episode featuring guest star Alan Cumming as Grouch explorer "Mucko Polo." Another episode is titled "When Dinosaurs Walked on Sesame Street."

Following the retirement of Fran Brill the previous season for 2015, Stephanie D'Abruzzo will take over over the role of Prairie Dawn and Jennifer Barnhart is cast as Zoe. In fact, Sonia Manzano will not be this season, although the new woman named Nina played by Suki Lopez. Music Director Bill Sherman revealed at the "On The Street Where You Learn" panel at Lincoln Center in January 2015 that a new version of the "Sesame Street Theme" would debut this season.
