A bird can fly and do a few other things, but a bird can't build a dam. A beaver can build a dam and more, but a beaver can't live underground. An ant, a tortoise, a monkey, and a camel become further links in Florian's chain before he closes the circle with the statement that a fish can't fly. Meanwhile small children have observed the habits of a few different animals, witnessed a demonstration of animal diversity, and absorbed an implicit lesson in the distribution of different-but-equally-useful abilities. All this to the tune of airy, mock-naive pictures that look about as didactic as a wall-eyed fish or a primate with a Halloween grin. Unprepossessing, but every element works.
