Animals on the Underground is the pet project of Paul Middlewick, begun in 1988. Paul found his first animal, the elephant, while he was staring at his tube map one day. From there, not unlike discovering the constellations, Paul kept finding more and more animals. Today, the animals having nearly taken over the underground, as the number of new creatures continues to grow. The animals now appear on clothing, bags, and bibs. Paul's original elephant is the star of his book, Lost Property, about "the helpful elephant who can't help losing his memory."
