It's Billy's Birthday, and Ruby Biggle needs the Kidsong Kids' help to put on a song-filled celebration. The fun begins when the kids meet Freckles, a silly little boy Biggle who takes them all around amazing Biggletown. Then it's party time as Billy leads the kids in fun games like Simon Says and the Limbo. Billy's a very happy boy when everyone serenades him with "Happy Birthday!" The kids can't wait to come back for more singing, dancing and Biggle fun, and you will, too!
