One Is a Snail, Ten is a Crab: A Counting by Feet Book
FROM THE PUBLISHER:
If one is a snail and two is a person, we must be counting by feet! Just follow the sign to the beach, where a bunch of fun-loving crabs, lounging dogs, gleeful insects, and bewildered-looking snails obligingly offer their feet for counting in a number of silly, surprising combinations -- from one to one hundred!
