Piper the Platypus Collar and Leash recognises an iconic species of Australia. Our one and only aquatic monotreme, Piper is an exceptional swimmer. He has a bill like a duck, a tail like a beaver and is quite a spectacle too see, if you can spot him. Piper is shy and, sadly, his species are susceptible to pollution in the waterways. Let’s clean up our act for Piper!
