I love the Mariah Carey Christmas song. It has a great dancing beat. But my favorite, non-traditional "fun" Christmas song is the "I Want a Hippopotamus for Christmas" song sung by Gayla Peevey in 1953 with lyrics and music by John Rox. Me and my kids break out into song in the car sometimes just singing "I want a hippopotamus for Christmas. Only a hippopotamus will do. No crocodiles, or rhinoceroses. I only like, hippopotamuses. And hippopotamuses like me too!!" It's such a fun song!
Here's an interesting fact about the popular Christmas hippopotamus song that I found on the Internet - "in 1953 a ten-year-old girl from Oklahoma, Gayla Peevey, sang the song as a way to raise money for the Oklahoma City Zoo's first hippopotamus. It became a nationwide hit after that, although John Rox wrote the song "I Want a Hippopotamus for Christmas" in 1950!
The song was not written specifically for the Oklahoma zoo, its just that when they needed the hippo, the song came out so the Christmas hippopotamus song just fit. The media, in order to raise funds, encouraged people to send their nickels and dimes to buy Gayla a "hippo" for Christmas. In December of that year the city received Matilda, the hippo, for Christmas. Isn't that a perfect example of the miraculous spirit associated with Christmas songs and the joy they spread."
I'm no choreographer, nor do I have a creative bone in my body, so I can't help you with ideas for how to create a dance routine or skit to this song. I just think it's such a cute tune and thought I'd throw that out there for you to consider.
Man, thinking about that song is putting me in the Christmas spirit already!! ;-)
Good luck!
