The Flintstone Kids

While babysitting Dusty Rubble, Fred and Barney (with the help of Wilma and Betty) finally get him to sleep. Mr. and Mrs. Rubble think they did a great job and make Fred and Barney take him to the carnival. While there, Dusty starts being a pain to Fred and Barney and disappears on them, and it's up to Fred and Barney to find him before the Rubbles come to pick him up.
