I got the idea after listening to the song this story name sake is from and some other elements similar.

Mares and gentlecolts
Foals and ghouls!
Step right up!
Behind this curtain lies a ghastly concoction of Delight, Horror, Fantasy and terror.
Your every wish is our command!
Your every whimsical desire brought to life
But I'm warning you, there's always a price!
Welcome to the greatest show unearthed!
