The Flintstones: The Surprise at Dinosaur Peak

The Flintstones: The Surprise at Dinosaur Peak is a video game for the NES created and published by Taito Corporation in 1993. The game was never released in Japan unlike its predecessor The Flintstones: The Rescue of Dino & Hoppy.

In this game, the player can switch playable characters between both Fred and Barney, and they both have different attacks and abilities; in the original, the only playable character is Fred. It is one of the rarest games to be released for the console, and is possibly the second rarest commercially released licensed title for the NES.

Original description:

Pebbles and Bamm-Bamm have wandered away from home and it looks like Fred and Barney found them. Unfortunately, an active volcano stands in the way. Now, Fred and Barney must travel across the pre-hysterical world of Bedrock to rescue the kids!

Fred swings a mean club and Barney's sling carries a nasty sting in this adventure for the whole family. Scale the side of a cliff, use crocodiles as trampolines, and leap into action as Bedrock's most famous citizens go looking for their children. Collect the hidden five fabled fire gemstones to pay a greedy Pterodactyl to return Pebbles and Bamm-Bamm to their homes!
