The Crypthaunt Recluse is a large spider feeding off of the residual arcane energies of magical artefacts. Any location containing magical items attracts them, but like most recluse spiders it prefers isolated places and is therefore most often found in especially rich crypts. They are intelligent enough to speak and reason with, thanks in large part to their saturation in arcane energies, but they cannot communicate verbally. Needless to say, any adventurer carrying magical items into its crypt is sure to draw its greedy attention. Instinct: To collect magic items

• Steal a magic item
• Pin down
• Scuttle away with treasure

An invasive species to not just the Mystery Islands but also the mainlands. These giant squirrels can readily drive out other species if not kept in check. Unlike their smaller cousins, they are omnivores and consider some stock and small humans and halfings a tasty meal. Beyond constantly storing food for the winter, they also are attracted to shiny things. They have figured out that dried food of humans in their barns or persons (Rations!) will keep well for the winter, and will face danger to obtain it if they think they can. Their big buck teeth can make them look cute, but pack a hellauv punch. Like their smaller cousins they flee when hurt, but will come back to get what they want. On the mainland and Halflings home they have all but been eliminated. Instinct: Invade the space taking all the food driving out other species

• Look cute and beg for food, before taking a chunk out of them
• steal their shiny objects or food and runaway to bury it
• Bark at them from up a tree or a from a distance driving all the predator animals in the party (dogs, cougars, hawks, etc) into chasing it.
• Run away when hurt going some way you didn't expect only to return later to get what they wanted
