Rudolph, are you asking me what "I Want a Hippopotamus for Christmas" is about? It's a song written by John Rox and recorded by Gayla Peevey in 1953. The song tells the story of a young girl who wants a hippopotamus as a Christmas gift. Despite her family's objections, she remains steadfast in her desire for a hippo, declaring that she will "sing that song until I'm big."
