After losing his job due to fighting with another employee, Huckleberry Hound finds a job offer in the newspaper that reads "We have a fabulous new job for you in Equestria, a peaceful world, and one that promises good pay. Positions available now!" Said job offer didn't specify what the job was, but the words "good pay" were enough for Huck. So he packs his bags and makes his way there, following the directions the map gave him. A bizarre portal trip later, he arrives in a world with colorful equine creatures, and learns from a hyperactive local that this is the Equestria the paper was referring to. Despite the weird new surroundings, Huck ends up getting a new job as a member of the Royal Guard thanks to Princess Celestia, and settles into a comfortable life with his new friends.

Of course, wherever Huck goes, trouble isn't far behind. Not long after starting his new job, a horrific monster from ages past is unleashed, turning ponies into crystals and consuming Ponyville with dark magic.

And Huck finds out that he's first in the line of defense to stop it.

Some "fabulous new job" this turned out to be.
