Spirou, Fantasio, and the Count of Champignac have decided to enter a competition organised by a rich ship-owner: to design a method for human beings to safely dive to and work at a depth of 200 metres. While the Count’s genius is up to the task, increasingly serious acts of sabotage begin to endanger his prototypes – as well as the three friends’ lives. Who could have a reason to put a stop to their endeavour – and what is the competition’s real goal, anyway?

To work in the same building as a walking disaster like Gomer is no picnic. Between his ‘fun’ chemistry experiments and his attempts at amateur rocketry, no one is spared – co-workers, secretaries, bosses, neighbours... We also discover that he’s just as dangerous outside of work: day at the beach or in the country, weekend between friends or romantic outing – there’s nowhere safe from the undisputed master of the goof!

At Spirou magazine, life goes on, punctuated by the occasional bouts of insanity of Gomer’s cats, attacks by Gomer’s gull, and disasters caused by Gomer’s latest invention … In other words, business as usual. And at least his coworkers can have some peace while he nods off at his desk! Outside of work, though, peace is not an option. Between Goof and Officer Longsnoot, the Parking Meters War has begun – and the winner will receive a twenty-one-goof salute!

Spirou and Fantasio are famous – among other things, as the official discoverers of that legendary creature, the Marsupilami, one of which often accompanies them on their adventures. So when one of their conferences is cancelled in favour of a documentary film from an unknown author, they are understandably irritated… until, that is, they realise the film is the very first to record the family life of wild Marsupilamis!

Welcome to the offices of Spirou Magazine. Everyone here is hard at work to keep the magazine ticking, from reporters to secretaries, including editor Fantasio and even, occasionally, Spirou himself. Everyone? Well, not quite... There’s that office boy, Gomer. No one’s entirely sure what his job description is, or how he got hired. One thing is certain, though: he’s a walking disaster zone! From work-shirking scheme to disastrous invention, enter the hilarious world of the most famous laya...

Nothing is ever simple with Gomer. Between his deplorable sense of timing, his absent-mindedness and his never-ending quest for new ways to avoid work, he causes a lot of fuses to blow – those of his colleagues, De Mesmaeker and poor Prunelle, of course, but also the actual ones at the office. And that is not at all to Alistair Bacus’s taste – the accountant at Spirou Publishing …

While on an expedition in Antarctica, the Count of Champignac makes an extraordinary discovery: a still-viable dinosaur egg! Having brought the precious find back to his castle, he invites a few colleagues over – along with Spirou and Fantasio – and sets about hatching the egg. But working towards scientific progress isn’t easy when one is somewhat absent-minded … and saddled with a whimsical Marsupilami ‘assistant’! Soon, life in the village of Champignac becomes rather complicated...

In Palombia, the president is throwing a lavish completion ceremony for a colossal project: a dam across the mighty river Huaytoonarro. An event that couldn’t leave the Marsupilami more indifferent, for he has other piranhas to fry: Mrs Marsupilami has disappeared. Our friend’s nose tells him that it was the doing of Bring M. Backalive, the famous hunter, and he rushes after the kidnapper, soon followed by Sarah and Bip … and then the situation becomes even more complicated!

The Marsupilami, a mysterious animal that Spirou and Fantasio discovered in the jungle of Palombia, now resides in their local zoo. When he seems to drop dead suddenly, the reporters storm into the park demanding explanations. Much to everyone’s surprise, though, the body has disappeared stolen! The two adventurers lose the thief after a night-time chase, but they will not abandon their friend, no matter where their loyalty may take them!

In Chiquito, capital of Palombia, there are nasty rumours flying of numerous orphans and poor kids going missing. And indeed, one evening, the son of a rich family is kidnapped along with a handful of street urchins after he sneaked out of school. The children are soon put to work in a clandestine gold mining camp. But the illegal prospectors are horrible polluters, and that’s already brought them into a very angry Marsupilami’s sights …

Deep inside the Palombian jungle, a rickety old boat sails up a sluggish river. On board is one of the world’s most famous hunters, and he’s vowed to be the first to capture a Marsupilami. But that’s no easy prey. The long-tailed creature is smart – much smarter than any human believes. And an alliance with the local natives isn’t going to be much help: they hate the Marsupilami who keeps outwitting them, and they’re desperate to find out what he tastes like…

Among the many obstacles to Spirou Magazine’s productivity, two of the most formidable are Gomer’s little protégés: a very playful cat and an evil-tempered black-headed gull. Between the bird’s dive- bombing attacks and the feline’s recurrent bouts of madness, Prunelle and the others don’t have it easy. And yet, none of that compares to the results of Aunt Hortense’s overgrown cactus being brought to the office by a clueless Gomer!
