Quackers is Ace Yu's duck puppet in Dog City. He was given to Ace by his father on his first (er, seventh) birthday.

Ace's father used to wave Quackers in baby Ace's face and say "Cluck cluck cluck, I'm a little duck." Ace eventually uses Quackers to defeat Bugsy Them, although as a result, Quacker's head was shot off.

The puppet was made out of a Rubber Duckie toy.
