Alligator!

Join Captain Lucy on a swampy adventure to answer a question from Terranauts Mateo and Emilio: what's the difference between a crocodile and an alligator? Discover which one is the bus-sized giant and which is more like a car, learn the smile secret that tells them apart (U is for alligator!), and find out why alligators live in only two places in the whole wide world. Full of clues, big toothy grins, and lots of fun — this is one mystery you won't want to miss!
