Quintacorn

Splitting from its ancestor, the quintacorn has shrunken in size and has evolved a third back spine. This evolutionary venture occured in order to survive better in its colder environment with smaller food and also to protect itself from larger predators. It will enter the water in order to feed on the flora in it, though they typically stay on land in small herds of 3-4 individuals. They breed twice a year and produce several offspring at a time which will stay with the herd until they're old enough to survive on their own.

During the colder months, they will use their claw-like frontal horns to break through the ice as well as to dig though the snow in order to get to the food underneath it, though when the temperature drops too low they will dig small communual burrows and hibernate until the weather gets warmer.
