Jibbins are interesting tundra-dwelling creatures best known for their rapid growth and shrinking, with their size determined almost entirely by their mood (and most recent meal). Although they generally keep a scarce diet of nuts and berries scavenged from the snow, jibbins that find themselves too excited for too long will grow to an unsustainable size for all but the most fruitful of environments. When hunting jibbins, many locals will intentionally antagonize the creature to induce rapid growth before killing it, resulting in more spoils per kill. When left alone in a calm environment, a jibbin can live up to ten years.
