LOL, no, no duck calls, just a regular high pitched squeaker, hahaha. I think the tip of the tail makes a crinkly noise too, if I'm not mistaken.... the body also has no stuffing. There's only stuffing in the head, feet, arms and wings, but not the actual body part - there's only a squeaker in there.
My boys love oversized toys too, and run through the house with them - it looks hilarious! I probably should have gotten the big one.... oh well, when they finish this one off, I'll get the big one!
