There is no "Sciuridae Swirlius" on ¾ÅÓÎÓéÀÖ¹ÙÍø's campus or anwhere else. Tri-color squirrels aren't possible in the way described in the original "IN A FLASH" post. Only black squirrels and gray squirrels can interbreed, as they are variants of the same species. Red squirrels are a different species of squirrel and cannot breed with black or gray squirrels.
Happy April Fool's Day, ¾ÅÓÎÓéÀÖ¹ÙÍø! (With apologies to the ¾ÅÓÎÓéÀÖ¹ÙÍø Department of Biological Sciences, who knows everything there is to know about actual species of squirrels and other animals.)
