The World’s Largest Rubber Duck Is Waddling Its Way To New York It’s a bird, it’s a plane, no it’s actually the world’s largest rubber duck (so technically I guess it is a bird) and it’s making a splash in New York from August 16-18 at Playland Amusement Park! To share with you the sheer size of this ducky, it towers six stories high, reaching more than a whopping 61 feet. But this duck is not alone. She’s accompanied by her duckling, also known as Timmy. But little Timmy is only tiny to Mama Duck as he stands 10 feet tall.
