Hydra (the moon of Pluto)

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
