AT THE WATER’S EDGE:

Only a duck-billed platypus will do
Don’t want a doll, no dinky Tinker Toy
I want a duck-billed platypus to play with and enjoy

I want a duck-billed platypus 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 platy hero standing there
[ Lyrics from: http://www.lyricsmode.com/lyrics
I want a duck-billed platypus for Christmas
Only a duck-billed platypus will do
No crocodiles, no hippopotamuses
I only like duck-billed platypuses
And duck-billed platypuses like me too

Mom says the platy would sting and poison me,
But Teacher says a platy is a harmless monotreme

There’s lots of room for him in our jacuzzi tub
I’d feed him there and wash him there and give him his back rub
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 platy hero standing there

I want a duck-billed platypus for Christmas
Only a duck-billed platypus will do
No crocodiles or hippopotamuseses
I only like duck-billed platypuseses
And duck-billed platypuses like me too!
