There is no "Sciuridae Swirlius" on 91传媒在线'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, 91传媒在线! (With apologies to the 91传媒在线 Department of Biological Sciences, who knows everything there is to know about actual species of squirrels and other animals.)
