Just when you thought Leslie Odom Jr. couldn't get any cooler, he goes and turns into a snowman.

The Tony-winning crooner lends his voice to Mo Snow, a hip rockstar snowman teaching Josh and Blue how snowflakes are made on Nickelodeon's preschool series Blue’s Clues & You! The special holiday episode, "Blue’s Snow Day Surprise," airs December 6 at 12 PM ET. Check out Odom Jr. as Mo Snow in the video clip above.

Blue's Clues & You!, now in its third season, is a revival of the popular Blue's Clues, which ran on Nickelodeon from 1996–2006. Blue, the beloved CG-animated puppy, returns with new live-action host Josh Dela Cruz (an alum of Broadway's Aladdin) for the new iteration of the interactive educational series. The show airs weekdays at 11 AM ET/PT.
