Does this put a smile on your face?

"Dancing With the Stars" is launching its mini spinoff "Dancing With the Stars: Juniors" on October 7. Last night, before eliminating the first couple of DWTS Season 27, "Juniors" introduced its young stars, dancers, and their DWTS pro mentors.

The young cast includes an "Avengers: Infinity War" star, a professional skateboarder, an ABC comedy star, a runway model, Disney Channel stars, and the youngest boy to compete in the Scripps National Spelling Bee.

You'll recognize some famous last names as the children of celebs -- or sister in the case of Mackenzie Ziegler, sister of "Dance Moms" star Maddie Ziegler.

• Miles Brown, "black-ish," with Rylee Arnold, mentored by Lindsay Arnold
• Ariana Greenblatt, "Avengers: Infinity War," with Artyon Celestine, mentored by Brandon Armstrong

There's already controversy about Mackenzie Ziegler's casting, since she does have quite a bit of dance experience. But they always love to cast at least one "ringer," you know that.

Hosted by DWTS Season 25 winner, Jordan Fisher and finalist Frankie Muniz, "Dancing with the Stars: Juniors" is judged by Emmy Award-winning choreographer Mandy Moore, professional dancer Val Chmerkovskiy, and "Dancing with the Stars: Athletes" champion Adam Rippon.

"DWTS: Juniors" premieres Sunday, Oct. 7 at 8 p.m. ET/PT on ABC.
