Chickadactyl
Chickadactyls are bizarre-looking creatures which resemble a cross between chickens and lizards. Chickadactyls were prominently featured in the Super Mario World episode "King Scoopa Koopa".
In "King Scoopa Koopa", King Koopa utilized several Chickadactyls to supply the eggs for his fast-food concession stand, "Scoopa Koopa". These eggs were used in his Special Scoopa Sauce, which could mutate other creatures into Chickadactyls, giving the recipient of this ingredient bird-like qualities and reduced intelligence. Koopa plotted to use these new Chickadactyls for a fried Chickadactyl stand once the transformation is complete in an attempt to make more money, but Mario discovers the Egg Scoopa Koopa scheme and shuts his operations down. After Koopa was defeated, Princess Toadstool dropped Koopa's Chickadactyls into a nearby Warp Pipe, which led to an unspecified location.
Chickadactyls were briefly mentioned by Koopa in a later Super Mario World episode entitled "Rock TV". After having brainwashed the populace of Dome City, Koopa's first command to his new servants is for them to "Cluck like Chickadactyls!". The cavepeople proceeded to do so.
