Pebbles goes into labor and they drive a bus towards the hospital with Big Rock, the real bus driver, and the painter of the bike the bus driver borrowed. There is a high speed chase which attracts the local cops. Fred finally makes it to the hospital and Pebbles is taken into the hospital fast. Big Rock, Rocky, and Slick catch up to them and Bamm-Bamm arrives to take them down as the cops arrest the crooks. Pebbles gives birth to twins, Roxy (who has muscular strength like her father) and Chip (who has his Grandpa Flintstone's mouth because he's another chip off the old Flintstone). As for Bamm-Bamm's script, Shelly Millstone got Bamm Bamm's script when Fred and Barney left it to her house. She loves the script and wants to star in it and Bamm Bamm sold his screenplay. Mr. Pyrite manages to get the script to Craig Craigmore and promotes Pebbles as Vice President. Fred and the others head back to Bedrock, leaving their children and grandchildren in happy harmony.
