McCluckington was a host in Stampy's speed building contest, and Squid said he had been with them for a long time.
Squid flew around and saw McCluckington on a cliff. He fell down and went towards Ninja's temple. Stampy and Squid were talking about the duck, but Stampy was holding wheat without realising. McCluckington then burnt and was buried by squid.
He looks like a normal duck/chicken.
