Professor Poopsnagle's Steam Zeppelin—also referred to as Professor Poopsnaggle and His Flying Zeppelin—is a children's TV series created through a collaboration between Australia's Reg Grundy Organisation and international partners including France's Revcom Television, the Netherlands' KRO, and Spain's TVE. The show premiered in 1986 on Australia's Nine Network, followed by broadcasts on Spain's TVE 1 in 1987 and the Netherlands' KRO in 1989.

The program was also distributed to viewers in Switzerland (TSI), Finland (1987), Greece (1988, ET1), France (1989, FR3), and Vietnam (1996, VTV3). Unlike its predecessor, Secret Valley, which saw limited commercial success in the UK market, Professor Poopsnagle's Steam Zeppelin enjoyed considerable popularity there. It first aired on ITV in 1987 and was subsequently repeated on Channel 4 in both 1990 and 1998, cultivating a dedicated cult audience.

The storyline unfolds over six distinct quests, each consisting of four episodes. Certain broadcasters, such as ITV Anglia, re-edited the series into feature-length television movies approximately 90 minutes long by merging episodes and trimming content to accommodate scheduling requirements.

Summary

Professor Poopsnagle possesses a crucial scientific secret but is kidnapped, endangering the continuation of his research. His young grandson, who assists him, teams up with Professor Garcia—a longtime associate—to pursue the kidnappers. Alongside a group of children from Secret Valley Camp, they construct a flying bus to chase their adversaries and complete the professor’s unfinished work. Guided by a decoded document, they confront various obstacles, including betrayal from within their ranks by Matt, who aids Count Sator and his accomplice. Despite these challenges, Professor Garcia and the children prevail, with Matt ultimately redeeming himself.

Part 1: The stranger arrives

Dr. Jose Calandre Garcia, engaged in research on Mega-steam theory, loses contact with Professor Poopsnagle and travels to Australia via hot air balloon to continue their work. Upon learning of this journey, Count Sator dispatches his agent Murk to bring down the balloon. Garcia survives the attack and is rescued by children at Secret Valley holiday camp, who decide to assist him in locating the six Mega-steam minerals.

Garcia’s sole clue is a telephone number; when he calls it, he reaches Poopsnagle’s twelve-year-old grandson. Together they commit to constructing a flying bus designed by Poopsnagle for the purpose of finding the minerals. Utilizing scrap materials from an abandoned nearby town and an old bus chassis as a foundation, they successfully build a steam-powered aircraft.

Count Sator responds by sending another spy named Willie Dingle and enlists Matt from among the children to act as an informant. Peter, Poopsnagle’s grandson, holds an ancient Latin cryptogram left by his grandfather. Decoding this leads them to discover the first golden salamander—a symbol marking mineral locations.

Each golden salamander contains cryptic messages directing them to subsequent sites. After uncovering the initial salamander near Secret Valley and surviving dangers such as a gas explosion inside a mine shaft, they find an uncharted valley where they locate the second salamander along with their first mineral.

Part 3: Stranded in the Desert

Upon returning to Secret Valley and decoding the newest cryptogram, Doctor Garcia and the children prepare to embark on their quest for the Rosy Prize, guided by the ancient Torres Parchment. Departing in the Poopmobile, Dingle is assigned to keep surveillance and promptly informs Count Sator of their movement. Matt aids Dingle in following the Poopmobile’s trail on the ground, but when the children sense they are being tailed, they take flight.

Count Sator directs Dingle to conduct aerial reconnaissance using a hang glider, while he and Murk head back to the Castle to deal with Poopsnagle, who has escaped his confinement. Although Dingle crashes during his flight, he succeeds in disabling the Poopmobile by popping its hot air balloon with darts provided by Matt. The children narrowly escape harm, but their vehicle suffers severe damage and loses its entire water supply from the steam turbine.

Jamie showcases his survival expertise by guiding Shorty and Sparks into the desert in search of water. While he manages to endure, the others become dehydrated until they are rescued by a traveling performer named Mr. Use-to-Was and his camel, who bring them back to camp. Utilizing pulleys from the bus alongside the camel’s strength, the children manage to extricate the Poopmobile from the sand. Jamie then employs plastic sheeting and solar heat to reclaim evaporated water trapped beneath the vehicle.

Meanwhile, Matt covertly transports a large water container from his own camp to replenish their reserves, much to everyone's surprise the following morning. Sator rebukes both Dingle and Matt for losing their water supply and orders an assault on the Poopmobile’s encampment. The attack is foiled when Jamie intimidates them by adorning himself with ceremonial paint that calls upon Aboriginal dreamtime spirits. Despite this setback, Sator succeeds in stealing Doctor Garcia’s Mega Steam notes during their pursuit of Jamie, delivering a severe blow to the team.

Heavy rain arrives the next day, refilling their steam accumulator and enabling them to take flight once more. Meanwhile, Count Sator becomes stranded in the desert. Carmen pinpoints their location as near the Rosy Prize, and after a windstorm scatters Sator’s stolen notes, the children recover both the prize and the salamander. Use-to-Was returns with additional notes retrieved from Sator’s van after exchanging his camel for Sator’s vehicle. Doctor Garcia and the children return victoriously to Secret Valley as Sator follows behind on a camel accompanied by Murk, Dingle, and a repentant Matt.

Part 4: Commando Raid

Back at Secret Valley, Doctor Garcia and the children work on decoding a cryptogram while Matt secretly copies its contents and plants a listening device that Dingle monitors nearby. Sparks discovers this bug and alerts the group, who then feed Dingle false information to mislead him. The doctor and children set out for a fishing village where two youngsters are trapped on a ferry, shadowed by Murk in disguise. Murk kidnaps Doctor Garcia and takes him to the castle where Sator interrogates him and imprisons him close to Poopsnagle—unaware of their proximity.

Suspecting Garcia’s capture, the children enlist police assistance to question Sator, who permits a dungeon search but finds no one. Poopsnagle briefly escapes but is soon recaptured. Under cover of night, the children launch an assault on the castle; they find Garcia but not Poopsnagle and end up trapped in a tidal cell designed to drown them. Tracking their movements, Matt assists in their escape through an air grate. They then board the Poopmobile and flee as Sator watches helplessly.

Once freed, Doctor Garcia and the children fly toward an island described cryptically as “joined by sand.” Using a metal detector, they successfully locate both the salamander and mineral before returning to decode their next clue.

Part 5: The Final Sprint

As the children approach a river bend resembling an M, they notice a bushfire and promptly rescue a man, a woman, and several animals. The woman pleads with them to locate her daughter Alice, who has gone off searching for her horse, Victory Stride. After safely delivering the rescued individuals to Rivers Bend, the group finds Alice; Carmen remains by her side while the Poopmobile provides aerial guidance. Sparks alerts nearby communities about the fire and unexpectedly uncovers the salamander attached to the Jambaroo Shield trophy, which is set for an upcoming horse race.

The children decide to enter Victory Stride in the competition but require a trainer. Meanwhile, Sator dispatches Dingle to acquire rival horses; he successfully purchases Black Eye along with its jockey to ensure his victory. Sid Chesney, a seasoned horse trainer convinced by the children, also knows the location of the fifth mineral—he was the one who initially discovered that salamander. After obtaining it, they find their bus has been sabotaged by Murk.

On race day, Sator is furious upon spotting Victory Stride arriving in the Poopmobile. Although Alice is unable to ride due to injury, Jamie steps up with Sid’s coaching. During the race, Dingle attempts to mislead Jamie using deceptive signs; Sator’s jockey resorts to throwing dirt and other forms of interference, but Jamie persists and ultimately wins with Sid’s timely assistance. They claim the salamander trophy but realize it bears no cryptogram. To make matters worse, Dingle has secretly installed a vision bug on the Poopmobile without Matt's knowledge.

Part 6: The Final Mineral

After returning from their latest adventure, Peter reveals the secret behind the last Salamanders cryptogram, which leads them to discover the final mineral hidden beneath the Sydney Opera House. Meanwhile, Sator keeps track of their actions through a vision bug and has coerced Matt into helping him steal both the minerals and Salamanders from Secret Valley in order to obtain the Doctor’s notes required for Mega Steam.

Although initially suspicious, the children decide to give Matt one last chance when they recognize his cooperation is critical. Using a vision communicator, Matt captures Sator’s voice to bypass security at the castle. To distract Sator, Carmen impersonates Divina Devaga—a European-accented antiquities expert—successfully deceiving him during a dinner at Roberto’s Restaurant. While Sator is preoccupied, the team retrieves the minerals, notes, and Salamanders from his stronghold. However, Sator returns prematurely and captures Peter, reuniting him with his grandfather under dire circumstances.

Unfazed, the Doctor and children identify water as the final mineral located at the Opera House. Back in their laboratory, they manage to produce a small quantity of Mega Steam despite receiving threats from Sator via Matt’s communicator. Powered by this Mega Steam-enhanced Poopmobile, they rescue Peter and Professor Poopsnagle from Baby Julius—Sator’s lethal pet. Following a confrontation with Sator and Murk, Dingle is dismissed and departs. Left exposed, Sator ultimately falls victim to Baby Julius as the team escapes with their precious cargo.

With Mega Steam’s secret safeguarded for peaceful purposes under the Geneva Convention, the Poopmobile stands ready for future missions.
