Disney’s Star Darlings is returning to TV in a new special episode that will premiere on November 26.

The 22-minute special, The Power of Twelve, follows the Star Darlings as they investigate the mysterious reason Starland is losing all power.

Following its TV debut, the first act of the special will premiere on YouTube on December 2. The second and third acts will premiere on December 9 and December 16, respectively.

Disney Consumer Products and Interactive Media (DCPI) launched the Star Darlings tween girl brand in August 2015. The property includes books, short-form web content, an app, dolls (from master toy partner JAKKS Pacific) and apparel.

The property’s first TV special, Becoming Star Darlings, premiered on Disney Channel in January, while a second special, Star Darlings Friendships, aired in March.
