Big Wide-Mouthed Frog by Ana Martin Larranaga
"I'm a big wide-mouthed frog and I eat flies," says the chirpy big wide-mouthed frog to the kangaroo, the koala, the possum and the emu. "Who are you, and what do you eat?" Then the big wide-mouthed frog meets a crocodile - and finds out that sometimes it's better to keep your big wide mouth shut! Fortunately this is a lesson he learns quickly and, puckering his mouth into the narrowest mouth you ever did see, he says, "I'm just a small narrow-mouthed frog and I'm off!" And away he hops.
