Size It Up Animals answer: September 26
The five Animals silhouettes for September 26, 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 23 ran from an axolotl (23 cm) to an elasmosaurus (10.3 m). The widest gap was round 1, Barn Swallow against Golden Retriever, at 3.1×; the closest call was round 2, Pink Salmon against Platypus, only 1.3× apart — the kind of round that separates a 90 from a 60.
