Hellhounds are dark creatures that inhabit the pits of the Underworld and punish the souls of the damned. Sometimes, they are sent out to drag the souls of the damned to the Underworld where they proceed to devour them over and over again. Sometimes, they are sent out alone, but others sent in packs. Either way, it's a terrifying experience to have a Hellhound hunting you. No matter where you go, a Hellhound will find you.

Frightfang is a Hellhound puppy who's simply trying to live his best life possible. Due to the nature of his species, he spends as much time fighting his siblings as he does playing with them. One day, a bunch of colorful mortal creatures actually come to the Underworld without being dragged there by one or more Hellhounds. When he accidentally follows them outside the gates, he tracks them back to Ponyville. The populace becomes terrified of the demonic pup. However, before the mob could do anything, a creamy Pegasus steps in and saves him.

How will Fluttershy handle a creature from a species that are naturally dark and destructive?
