The child has fair hair, falling in fleecy waves to its shoulders, but not particularly groomed. It has delicate features, rosy cheeks, and round blue eyes. For clothing Chick wears white garments like pajamas, with wide flowing sleeves and legs, and sandals to protect the feet. Chick claims to be six years old, but has been making that claim for several years.
Chick is known as an Incubator Baby because the child has no parents. The name "Chick" comes from chickens, which are usually raised in incubators.
Chick lived in a third-floor apartment, in the Royal Palace of Phreex.
Chick met John Dough when the Gingerbread Man visited the Isle of Phreex, befriending him and showing him around the island and introducing him to the interesting residents. When Ali Dubh appeared and tried to eat John, Chick escaped with him aboard a flying machine built by Imar.
After a long flight over the ocean, they landed on the roof of the Palace of Romance. They were invited to tell all the stories they knew, and were warned that when the stories stopped, they would be thrown into the ocean. With boundless imagination, Chick began to create stories about the Silver Pig of Dagupan. After many days of storytelling and nights of searching, John and Chick were able to find their flying machine and escape the island.
They crashed on the Isle of Mifkets and befriended a rubber bear named Para Bruin and a sickly Princess named Jacquelin. John and Chick risked their lives trying to protect the Princess from the primitive natives, and were helped by the King of the Fairy Beavers. The Beaver King later helped John, Chick, and Para Bruin escape Mifket Island aboard a flock of Flamingos.
After a brief stop on Pirate Island, they finally landed on the island of Hiland and Loland. Chick explored the twin kingdoms and learned that they were awaiting a prophecied king whose description matched that of John Dough perfectly: a man not made of flesh and blood. John was crowned king and Chick became his Head Booleywag. (John Dough and the Cherub)
