There are just a couple more days until the Switched at Birth Christmas special airs where a promo was released in sign language on what's about to take place.

Daphne 'Mixes It Up' With New Character On 'Switched At Birth'

The promo that was posted on Friday shows Lea Thompson (Kathryn) singing "Jingle Bells" with different words added to the song. The clip starts off with Thompson singing about the story of how Bay and Daphne went to the wrong parents at birth as she uses sign language for the song that sounds like the famous Christmas jingle.

The clip moves on with other actors from the show, including Katie Leclerc (Daphne) who signs that the parents took the wrong girl home.

Actress Says 'Switched At Birth' Christmas Episode Will Have 'Magic'

As for what's going to happen in the holiday episode, the girls are apparently going to make a wish to have each other's lives, which ends up coming true.

"They share a garlic knot that might have been bewitched," the song goes. "And wake up in the morning like their lives were never switched."

This leads to Bay and Daphne fearing that they'll be stuck this way. And according to the Christmas jam, "they have to get the curse reversed before it's Christmas Day."

The cast members are signing together for this last moment as they wear random Christmas hats and use little instruments.

The Switched at Birth Christmas special airs on Monday, December 8 at 9 p.m. ET on ABC Family.
