Pelle and Pingo agree to help Rasmus build a boat to Old Salt.

Rasmus and his friends go exploring aboard the Mary. Suddenly, they find themselves atop a mysterious island.

Rasmus, Pingo and Pelle are rolling barrels along the coast, as they discover that the good ship Mary hadn’t been properly tied up and has now disappeared. Old Salt explains that the current can quickly pull boats out to sea. What to do?

On board The Mary, Rasmus peers through a telescope at a passing island and discovers a family of kangaroos: Peter and Betty with their little one. Peter proudly shows Rasmus the car he’s building.

Sailing with the good ship Mary, Pingo discovers a bottle full of confetti and a promo flyer from Pete Peterson’s Party Island. This makes him come up with the idea of a surprise party for Rasmus.

The friends aboard the good ship Mary come to a small, peaceful island covered in sand dunes. Suddenly, Pingo hears a cracking sound. The noise is coming from an egg and he watches a turtle hatch from it.

Rasmus, Pelle, Pingo and Old Salt are in Antarctica. Rasmus, Pelle and Pingo trudge through the ice and snow, dragging a sleeping Old Salt behind them. He is fast asleep in his rocking chair. It is their dream to see the northern lights.

Pelle, Rasmus and Pingo set out on a treasure hunt. Rssmus and Pingo are dreaming of what might be in the treasure chest. Pelle just wants to prove to his Uncle Bruno that he can find the treasure.

Rasmus, Pingo and Pelle go to the mountains. Rasmus falls into a crevice, but lands on the shoulders of the polar bear Greta who is an experienced mountaineer and offers the friends her help.

Rasmus is on deck. He is having fun setting the table in his own messy way. He then goes to the galley to make pancakes. Meanwhile, the raccoon Addi is preparing for the perfect, romantic dinner.

Mary is tied to a river bank in a jungle. Pingo has lost his voice and Rasmus wants to help him and find out what it is he wants. Maybe he wants pancakes for breakfast?

It’s unbearably hot, and Rasmus, Pingo and Pelle roll their empty water barrel down the Mary towards a well in the distance. They find an abandoned railway track and they meet a crocodile lady conductor.

On board the good ship Mary, Pingo notices something strange. It’s a thick rope stretching from pole to pole blocking the entire ocean. What is that?

At the soap box race, only those who pass a test may take part. Pelle and Pingo find that easy, but Rasmus fails. Old Salt takes care of his friend. But Rasmus does not want to accept that a soap box needs a brake.

The friends drive a band to their first big gig. But the music the band plays is so quiet that their performance is not fun to watch. The friends quickly enthuse two of the three band members to play louder and more impressive melodies.

The friends come to visit Pingo's grandmother. On the very last day of the lifeguard course for the young penguins. The little penguins are supposed to jump after one of the adult penguin from a high cliff - deep into the sea.

When a storm puts Rasmus and his crew on a deserted island, there are two problems to solve: Old Salt has disappeared on the Mary, and a monster makes the whole area unsafe.

While the friends go to a dark forest to collect berries, Pingo stays on the ship. He is afraid of trolls. And he is not alone. The scared bunny Emma is afraid of trolls, too.

The friends lovingly take care of young chicken Kurt, who's birthday is today. But Kurt seems to have a problem. He wants to fly - and fails again and again.

Deep in the mountain, the friends come across a strange room, a wizard costume and a barrel organ. What's its purpose, they do not understand. Especially not when suddenly there is no escape.

Old Salt has invited his friends to watch a fish ballet in his submarine. But Old Salt shifts the appointment as he suddenly leaves without comment and disappears with the Mary.

The friends want to camp. But then they run into kids, who tap their foreheads with their hands. Rasmus, Pingo and Pelle do not understand what that means.

In the middle of the desert, the friends enter a half-sunken building. It's not a pyramid, and the dead mummy inside is a very lively hippopotamus called Nils. Nils has desperately tried to dig for a spring in the basement of the house.

The fluffy lambkin caught Pingo's attention. Rasmus fears that his best friend will have no interest in him anymore so Rasmus tries really hard to prove to Pingo that it is more fun to hang out with him than with lambkin.

Old Salt visits his old friend, the king. While the two reminisce on the Mary, turn Rasmus, Pelle and Pingo Princess Ursula's world in the castle upside down.

It's New Year's Eve, and Rasmus is looking forward to the party and the fireworks. But when he suddenly gets sick and even Doctor Stork can hardly help him, the ingenuity of the friends is needed.
