Season 1

In this, the very first episode of Hanna-Barbera's first TV show, our heroes read reports of spacecrafts from other worlds. One such ship bears a bead on Ruff and Reddy as they nap and take them aboard the craft.

Ruff and Reddy awaken from their nap to find they have been taken hostage by the ship from space.

Ruff and Reddy's robotic captors pursue them with a gun that Reddy gets hold of.

On the metal planet Muni-Mula ("aluminum" spelled backwards), Ruff and Reddy face a two-headed metallic chieftain called "The Big Thinker," who takes our heroes to be assimilated as metal clones.

The duplicating process of Ruff and Reddy begins. Reddy tries to intervene but becomes a robot himself after he gets zapped by the robot brain implanter.

Ruff tries to help Reddy but is followed by a roving mechanical spy.

Reddy gets accidentally mesmerized by the brain waves and under orders of the Big Thinker takes Ruff captive.

Ruff and Reddy discover a scientist, Professor Gizmo, in the dome of the Big Thinker. Gizmo tells how he blasted off in his homemade rocket and was taken prisoner in Muni-Mula.

After Reddy destroys the slumbering inner works of the Big Thinker, he, Ruff and Gizmo are hunted down by a huge robot centurion.

Reddy, having given the Gizmo 2 ship a boost, is left behind on Muni-Mula. Ruff and Gizmo go back after him but are confronted by a flying attack squad of Muni-Mula robots.

Gizmo confuses the Muni-Mula attack squadron by cloaking the Gizmo 2 craft in a dark cloud. Meanwhile, Reddy takes off in one of the metal squadron's head propellers and is mistaken by Gizmo to be one of the metal men.

Gizmo rescues Reddy from his freefall, but now the Gizmo 2 rocket ship is on a collision course with a meteor.

The meteor hits the Gizmo 2, sending it and our heroes on a crash course to Earth, where broadcast media reports its arrival as if it were a UFO invasion.

A baby elephant escapes from a circus and requests Ruff and Reddy to take him home in Africa.

Ruff, Reddy and Pinky board Voo Doo Queen and get locked on board.

Captain Crossbones Jones forces Ruff, Reddy and Pinky to be his crew, but they start to escape.

Ruff, Reddy and Pinky get stranded at sea trying to escape and then they start to sink.

Ruff, Reddy and Pinky cruise to an island. Ruff gets captured whilst exploring.

A hunter named Harry Scary uses Ruff as bait to lure a lion, but the lion and Ruff take off.

Ruff rescues the lion and Harry Scary reveals himself as an elephant hunter.

Before Harry Scary can shoot Reddy, the lion comes to his rescue and all three run for it.

Ruff, Reddy and Pinky escape from Harry and try to get across a river. Their escape log turns out to be a crocodile.

Reddy gets trapped with the crocodiles after saving Ruff and Pinky and Harry Scary comes round.

Ruff and Reddy follow Harry Scary who took Pinky away. Harry Scary makes Pinky lure his mother into a trap.

Harry Scary gets all Ruff, Reddy, the lion, Pinky and his mother exactly where he wants.

The tables turn because of Harry Scary's empty rifle. Ruff and Reddy stowaway back home.

Reddy wins a trailer, so he and Ruff take a vacation to the Grand Canyon. An accident, however, sends them to the ghost town of Gruesome Gulch.

Ruff and Reddy are spooked by Gruesome Gulch's ghosts, which are actually fake ones manipulated by two rustlers.

Ruff and Reddy meet Wooly, a sheepdog whose flock of sheep is being mysteriously stolen. Reddy is coerced into posing as a sheep to catch the thieves.

The sheep thieves in a helicopter pluck Reddy from the flock and take him to Gruesome Gulch.

The thieves, sibling outlaws Killer and Diller, aim to sheer the sheep of their wool, which threatens Reddy's cover.

Reddy's cover is blown. Killer and Diller tie him up, place him in a mine's ore car and sends him towards an unfinished section of the trestle.

Ruff and Wooly rescue Reddy, and together the three heroes head back to Gruesome Gulch to find Wooly's sheep.

As Ruff, Reddy and Woolly pursue the Texan Twins, they get flat tires and take the helicopter for transport.

Reddy lands on the truck's roof where he holds Killer at gunpoint. But Reddy ends up getting clobbered by a tunnel's low clearance.

On Killer and Diller's secret ranch, the Double Cross, the sheep spell out the word "help" for our heroes. Unfortunately, their copter has run out of gas.

Thanks to the sheep, our heroes find the copter's safety chute for landing safely. Once landed, Killer and Diller capture them and lock them up.

In accordance with the rules of the west, Wooly demands that he and his friends fight for their lives. So he volunteers Reddy to a duel with Killer and Diller.

Reddy nervously faces Killer and Diller in the duel, but he has an ace in the hole: Ruff in his cowboy hat with a second revolver.

At an aquarium, a baby seal follows Ruff and Reddy home. A chase ensues when the aquarium announces a reward for the seal's return.

The chase for the seal leads to a pier near the ocean, where someone underwater is in trouble.

The metal monster Ruff and Reddy hoist to land is a diving bell, and in it is Professor Gizmo, who is mining for gold beneath the sea. Meanwhile, a periscope spies our heroes.

The periscope belongs to a mysterious submarine that trails Gizmo's ship, the S.S. Leadbottom, which is on the way to a pirate's treasure.

The submarine captures Gizmo's diving bell with a giant magnet and takes it to a mysterious grotto.

Captain Greedy and Saltwater Daffy imprison Ruff, Reddy and Dr. Gizmo. Then the seal arrives to help them.

The seal helps Ruff, Reddy and Gizmo escape and leads Greedy and Salt Water Daffy on a merry chase.

The crew attempts to escape on Captain Greedy's sub, but are recaptured. Greedy forces Ruff and Gizmo to mine for treasure while Salt Water Daffy keeps Reddy and the seal at bay.

The seal saves Reddy from drowning but Saltwater catches him.

The seal and Reddy manage to get away from Saltwater but are tailed by a shark.

Reddy and the seal escape but are being pursued by a shark. A friendly whale scares off the shark and takes Reddy and the seal to help Ruff and Gizmo.

The seal boards Dr. Gizmo's sub with Ruff inside it and prepares a surprise for Greedy.

Greedy gets all the gold, but when he makes Reddy give back the doubloon he was going to keep as a souvenir, Greedy's ship sinks from the weight.
