The Qwack-O-Ray is a Gadgetron weapon that can turn enemies into ducks, which Ratchet can acquire for the first time at the Outpost X12 of planet Aridia. From level 2 on, the transformed ducks lay eggs that will approach and detonate near the closest enemy. When upgraded to Quack-O-Blitzer, the first transformed duck becomes a huge Phoenix and will fly around Ratchet and Clank destroying enemies.
Ratchet cannot use the Quack-O-Ray while jumping or crouching.
