Merry-Okee allows you to change your voice to sound like an elf – a fun activity for the whole family! This Christmas karaoke microphone features six pre-recorded holiday songs to sing along to – “O Christmas Tree,” “Deck the Halls,” “We Wish You a Merry Christmas,” “Jingle Bells,” “Jolly Old St. Nick” and “Up on the Housetop.” Includes a song book with original lyrics as well as parody lyrics to add some silliness.
