The group quickly learns to change diapers and pilfers milk bottles to keep the child fed. Investigating the stolen bottles, Dibble finds out about the infant. Later, when the baby's mother asks the policeman for help regarding her missing child, he reluctantly takes the baby away from Top Cat's gang, who tearfully say goodbye.
