Over all I found the host of the festival refreshing for while they did glamour-ize faeries in an overly positive and more intellectual light then I would prefer. They also showed the true threat of the unseelie folk, and often spoke of changelings and infant snatching.
I was also excited to have added to my collection a "Mud Goblin"

They Have announced Due to the rarity and difficulty of this genus of goblin they have been limited to 500 of these darlings being hatched and raised to a suitable age for homing with prospective keepers and cryptozoologists.
While at first I was deeply concerned with the social interaction of my new Mud Goblin with the Mediocris I currently keep in my lab, along with the "Noise Goblin" I had brought home the year before for my off spring to study, and of course our House Brownie Dizmil, Who tends to have a pention to upset the less domesticated of the fae, I can report there has been little issue with it's incorporation to our homestead. While I do question the claimed birthing of the Mud goblins by Goblin road's as they claim they are spawned in a form of Laughism "Where as we all know that faeries are born from the laughter of children, Mud Goblins are created everytime a child squishes mud, muck, goop, or grime between their toes and delights at the squelchy sound."
They do however come with a certificate of their pedigree, insuring they are true goblin of merit.
Over all I would advise getting one of these rare genus of goblins before their hatching season passes and it is another long century before their breeding season commences once more.
