Follow along with National Geographic explorer Brady Barr as he crawls into a muddy hole just barely big enough for his shoulders, and comes face to face with thirteen crocodiles! Laugh out loud as you learn how to catch a crocodile using shoe laces and underpants. Read in anticipation to find out what happens when you put a 600-lb crocodile on an airplane in just a flimsy wooden crate. These action-packed stories and more will engage readers and inspire them to go out and explore their own world. Stories include: - "Undercover Croc," in which Brady "becomes a crocodile," by donning a specially-designed protective croc suit, and infiltrates a group of Nile crocodiles in Tanzania. - "Toy Story," in which he uses (and loses) a radio-controlled car with video camera, in a hilarious failed attempt to capture a Nile crocodile in South Africa. - "Deep Dark Den"--in an attempt to relocate a group of crocodiles causing problems to neighboring villagers in Costa Rica, Brady finds himself underground in a deep muddy hole with thirteen angry crocs. - "Croc in a Box," Brady tries to move a giant, troublesome croc from Uganda safely to an American zoo, but discovers the croc is much stronger than the "sturdy wooden box" that has been built to contain him.
