GREEN BAY -- The world's largest rubber duck is joining in on the fun at Green Bay's Tall Ship Festival.
According to WLUK, the giant duck known as "Mama Duck" weighs 11 tons -- roughly the weight of 5 1/2 cars -- and weighs more than the heaviest elephant ever recorded in the world.
Mama Duck will float alongside nine ships for the 2016 festival.
The annual festival runs from August 5-7.
