The Flintstones: Little Big League
Little Big League features a pre-teen Pebbles and Bamm-Bamm voiced here by Frank Welker in prominent roles, but the main plot revolves around Fred and Barney of course. Fred is upset because Barney can’t go bowling with him, because Barney is coaching Bamm-Bamm’s little league team and forging a great father-son bond as well. Pebbles is feeling left out because Bamm-Bamm and Barney are doing things together, while Fred just ignores her, too busy being angry at Barney to notice. Wilma and Betty come up with a great plan for peace — Barney should offer Fred a job on the team. Barney misunderstands, making Fred madder, until he declares the families are not to see each other again. Of course, everybody ignores him.
Next day at work, Mr. Slate offers Fred the chance to coach his new Little League team. Pebbles asks to be on the team, but Fred pulls the old “girls don’t play baseball, girls cheer on the team” crap, so Pebbles and Dino end up sitting in the stands. Of course, Pebbles secretly has mad baseball skills, which Fred eventually discovers and exploits when Pebbles becomes the team’s phenom pitcher.
