There is no "Sciuridae Swirlius" on 91²Ö¿â'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, 91²Ö¿â! (With apologies to the 91²Ö¿â Department of Biological Sciences, who knows everything there is to know about actual species of squirrels and other animals.)
