Not Your Average Rubber Ducky! Kids are all different shapes and sizes, shouldn't rubber ducks come that way too? Meet Slim, Bob, Jane and Squish, from Boon. We're not trying to encourage a rubber ducky smackdown, but Boon Odd Ducks are PVC and phthalate-free, and no BpA either, unlike those other mucky ducks. And Boon Odd Ducks do not hold water, so they won't grow that black mold that kids always try to suck out. Boon Odd Ducks Collection includes Slim, Bob, Jane and Squish.
