The only thing Tuck doesn`t like about swimming lessons is the water. He worries that water might get in his ears and feel awful. Or it might get in his eyes! You`ll get used to that, says his mom. Your eyes are waterproof, says his swim teacher. I`m not going swimming, says Tuck. So no one is more surprised than Tuck when he heroically takes the plunge--and finds out he can get into the swim of things after all.
