They call me Hydra but I'm not a snake
And I'm not a dragon or a fake
I orbit around Pluto for old times sake
For I'm just a space dog who loves cake
I may not look like it with this bod
And I don't have any remnants of my pod
But there is nowhere on Pluto that I have not trod
For I am a digitalized orbital god
I am the only D.O.G. the number one
I may seem lonely from my tone
But I have plenty of friends I call my own
When ever I need a number two
Charon is always willing to help me through
There is Nix and Styx and Kerberos too
We are merry friends, an amazing crew
How lucky are we, our friendship is true
How lucky are we to be Pluto's moons
