Lyrics:

I want a hippopotamus for Christmas
Only a hippopotamus will do
Don't want a doll, no dinky Tinker Toy
I want a hippopotamus to play with and enjoy
I want a hippopotamus for Christmas
I don't think Santa Claus will mind, do you?
He won't have to use our dirty chimney flue
Just bring him through the front door
That's the easy thing to do
I can see me now on Christmas morning
Creeping down the stairs
Oh, what joy and what surprise
When I open up my eyes
To see a hippo hero standing there
I want a hippopotamus for Christmas
Only a hippopotamus will do
No crocodiles, no rhinoceroses
I only like hippopotamuses
And hippopotamuses like me too

Mom says the hippo would eat me up, but then
Teacher says a hippo is a vegetarian

There's lots of room for him in our two-car garage
I'd feed him there and wash him there and give him his massage
I can see me now on Christmas morning
Creeping down the stairs
Oh, what joy and what surprise
When I open up my eyes
To see a hippo hero standing there
I want a hippopotamus for Christmas
Only a hippopotamus will do
No crocodiles or rhinoceroseses
I only like hippopotamuseses
And hippopotamuses like me too
