Yabba-Dabba-Doo! is a video game based on the original series, The Flintstones, for Amstrad CPC, Commodore 64 and ZX Spectrum released in 1986. It was developed by Quicksilva Ltd. and published by Taskset Ltd.
Yabba-Dabba-Doo! is set before the marriage of Fred and Wilma Flintstone, during a time when the city of Bedrock was beginning to take shape. Playing as Fred, the player's goal is to build a house and persuade Wilma to move in with Fred, leading to their marriage.
The player begins with a plot of land that is covered in small rocks, which must be carried off one at a time and dumped into a nearby pit. Enemies include Pterodactyls that try to drop rocks on Fred's head, and Turtlesauruses and dinosaurs which harm Fred directly. After clearing the rocks from the land, the player then searches Bedrock for boulders, which are used to build the house. Once the house is ready for a roof to be added, the player must get a job at a quarry in order to raise money to hire a dinosaur service, which will allow Fred to reach the top of the house. Throughout the game, Fred must meet with Wilma whenever he comes across her, in order to fill a heart meter which demonstrates her love for him. When the house is complete, the player must find Wilma and get her to follow Fred to the new house, which she will only do if the heart meter is full. Kissing Wilma is also the player's only way to refill the health bar.
Bedrock is represented through various screens. The player can move left and right to maneuver between screens located along the same path. Accessing upper and lower screens is done by moving diagonally towards the corner edge of each screen, rather than walking straight up or down. Located within Bedrock is Fred's car, which provides faster transportation between screens if it is found by the player. Buildings in Bedrock include a service station, a burger bar, a drive-in movie theater, and a health club, with the latter three locations being popular hangouts for Wilma. Fred's neighbors are building their own houses, and the player earns bonus points if Fred's house is finished before the others.
- The video game's title was used and based on Fred's iconic quote and trademark of the same name.
