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