Skullcrusher Mountain.
I made this half-pony half-monkey monster to please you
But I get the feeling that you don't like it
What's with all the screaming?
You like monkeys, you like ponies
Maybe you don't like monsters so much
Maybe I used too many monkeys
Isn't it enough to know that I ruined a pony making a gift for you?
