The Managerie in the Hole

Although very happy to have all her new friends back, Rosey isn't all that sure of the beasts and creatures that they've dragged back with them.
Issack, the magical, talking backpack has become a true friend and, although he's been feeling a bit low due to the loss of his stick-man servant; Cary, he's always ready for a chat and full of useful items and good advice.
Sereena's smokey cat; Cogitari is a blessing. She's proved to be a terrific little mouser and, when not curled up near the fireplace, is a clever and vigilant, much petted guard.
The wolf, whom she found scratching at her door, is another shaggy but welcome addition. She'd recognised him immediately as Greyclaw, the young barbarian; Volkon's pet and, despite her initial fear, shepherded him into the small open-aired storage area at the back of the Inn.
After winning him over with food scraps and attention, he now acts as the honorary 'doorman', deterring (alongside her recently hired half-orc bouncer; DeTrop) any unruly behaviour in her bar.
The most recent addition though, leaves her less than thrilled.
The handsome elf; Nitendae had returned with a hideous, bulbous, one-eyed creature in tow.
Literally in tow!
Floating over his head, on a length of fine chain, the creature's toothy maw hangs open and drooling. A slender, hooked harpoon piercing it's flesh, holds the chain in place and, apparently, makes the terrifying creature docile.
Nitendae's been using it (in combination with his magical levitating boots) to drag himself through the air all over town!
He says he loves the freedom the monster grants him but, despite his protestations, Rosey can feel an evil, frustrated malevolence emanating from the blobby bobbing thing.
It gives her the heebie-jeebies...
