The Man Called Flintstone is a 1966 American animated musical comedy film produced by Hanna-Barbera Productions and distributed by Columbia Pictures.

In the opening scene, a man physically identical to Fred Flintstone, later revealed to be secret agent Rock Slag, is being chased through Bedrock.

After Ali and Bobo find Rock and put him out of commission, Chief Boulder of the Secret Service enlists Fred to take his place in Paris for a special meeting.

Discovering the Chief's secret office, Fred tries to back out of his assignment but after finding out what the Green Goose really is, he has pangs of guilt over Pebbles' future and makes an excuse to get away and meet Tanya at a restaurant.

Tanya then leads Fred to the Green Goose (whose hideout is at an abandoned amusement park), but he is unaware that the Chief has been taken out by Ali and Bobo, so he has no back-up.

Triple X, who is revealed to be The Green Goose, makes plans to launch his deadly inter-rockinental missile, which is disguised as the park's space ride.

When he offers to release them in exchange for it and opens the door, the boys turn the tables on the Green Goose and lock him in the missile with Ali, Bobo and Tanya—with the target now reset for outer space, sending them all to an unknown fate.
