is the fraternal twin brother to Roxy Rubble, the son of Bamm-Bamm Rubble and Pebbles Flintstone, and the grandson of Fred and Wilma Flintstone, and Barney and Betty Rubble.
Chip and his twin sister, Roxy, were born at the end of Hollyrock-a-Bye Baby. Chip looks just like his father, Bamm-Bamm, but he has red hair like his mother, Pebbles, and he also inherited his loud mouth from his maternal grandfather, Fred Flintstone.
