"This is the bell on the school in the bay. Ringing the children in from their play. This is the teacher, holding her chalk, telling the class, "Sit straight! Don't talk!" This is the board, as black as soot, and this is the snail with the itchy foot! "A snail! A snail!" The teacher turns pale. "Look!" say the children. "It's leaving a trail." This is the trail of the tiny snail, a silvery trail saying, "SAVE THE WHALE."
-The Snail and the Whale by Julia Donaldson
