I believe the technical term for this would be: "mysterious round thingy." Seriously. I don't even know how to google it because I have no idea what to type in. Is it some sort of nest?? Have you ever spotted this during your WDW wanderings? And if you know what it is you get massive bonus points!
Good job to everybody who guessed last week's list of wacky names. You'll find Buckaroo Burke and Calamity Clem in the stand-by line at Big Thunder Mountain Railroad!
