my mother wants a hippopotamus for christmas

Recently my mother told me about a Christmas song about a little girl who wants a hippo for Christmas. She even sang some of it to me over the phone. I had never heard of the song, but we agreed that we would try and find it while I was at their house over Christmas on their new computer. Well, we did find the song and it is very catchy. I find myself singing it quite a lot.

Steven received a thing that plays this sing when you push the button, so I am going to crown this year "The Year of the Hippopotamus Christmas"!
