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
