The Flintstones: The Surprise at Dinosaur Peak!

In this platformer sequel, Fred and Barney must rescue their cartoon children, who are trapped behind a waterfall of lava, by traveling to Dinosaur Peak. The player controls Barney and Fred both at the same time, and can swap out one for the other on the fly via the Select button. Fred is armed with a powerful clubbing attack (which can be charged up) to whack the prehistoric enemies, and has the ability to climb and lower himself from ledges.
