The Flintstones and the Rubbles find out their children, Pebbles and Bamm Bamm, will soon be parents.
Pebbles and Bamm-Bamm, now married, soon become blessed: Pebbles is pregnant, so the Flintstones and the Rubbles go to Hollyrock to stay with them, Fred renting a new RV for the occasion. Wilma, Betty, and Fred fuss over poor pregnant Pebbles and won't give her a moment's peace. The excitement of being grandparents is strong; also along is old lady Pearl Slaghoople, Wilma's mom, who will soon be a great-grandmother.—Dylan Self <[email protected]> (Corrected by Anonymous)
