Size It Up Animals answer: October 31
The five Animals silhouettes for October 31, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.
Day 58 ran from a copepod (3 mm) to a hippopotamus (3.5 m). The widest gap was round 2, Dodo against Hippopotamus, at 5.6×; the closest call was round 5, Bottlenose Dolphin against Bull Shark, only 1.2× apart — the kind of round that separates a 90 from a 60.
