Year 1997

Plummy is happily floating on his lilo on the pond. Pliff and Plops ruin the peace and quiet by driving so close to him on their motor boats, that Plummy falls and sinks. Underwater, he grins and turns himself into a huge drain and pulls the plug out by himself, whereby the pond water drains away like a huge whirlpool and Pliff and Plops are left sitting on dry land. Remorsefully they turn themselves into a pump, and fill up the pond again and in no time at all, all three of them are sitting on a huge lilo for three.

Plummy builds a gondola and waits for some customers. Pliff and Plops want to have the gondola all for themselves and so they throw Plummy overboard. Plummy camouflages himself as a beautiful Venetian lady and confuses Plif and Plops. Both of them fall in love with her and fight for her using roses and mandolin music. They become fierce rivals and after a fight, land in the water. Plummy saves them both and they all become friends again and enjoy a romantic trip in the gondola.

Pliff and Plops are envious because Plummy has a chemist's experiment set and they don't. They play around with a test tube and a very wild blue-green mass pumps out of it, together with bouncy balls. Of course, Plummy catches on and shoos them away in the form of a huge orange foam. But then they've all had enough of experimenting and get together again with a glass of lemonade!

While visiting a knight's castle, Pliff and Plops take the opportunity of doing a horror show: after a wildly shaking drawbridge, living pictures and knight's armoury, Plummy realises who the ghost is and takes revenge with a comical spook number!

Plummy makes a classic Greek sculpture and makes it so pretty that he falls in love immediately. Pliff and Plops want to tease him and turn into other, prettier statues. Plummy falls in love with the new statue on the spot, which suddenly come alive ... and ticklish. And because it's so funny, the three of them turn into a super statue and put the camera onto automatic and take a picture of themselves.

Plummy models himself a ship and a captain's hat and goes on a sea voyage. Pliff and Plops are envious, become pirates, follow him and capture his ship. As a huge octopus, Plummy gets his ship back while Pliff and Plops flee from the octopus to the nearest island. Luckily, they don't have to wait long: Plummy picks them up and takes them to the mainland!

The Plonsters want to have a picnic in the autumnal forest and have barbecued chicken. In order to fan the fire, Pliff turns himself into a large ventilator, turns himself onto turbo speed and becomes the cause of a forest fire. They have to call out the Plonsters fire brigade: Plummy as a fireman, Pliff as fire engine, Plops as the water hose. And from now on, chickens will only be cooked in the microwave.

Plummy, as a bird, is being hunted by Pliff and Plops. They pull two feathers out and play Red Indians with them. In order to get his feathers back, Plummy turns himself into a huge vulture and takes the other two on a very uncomfortable flight, before the other two give him a banana as a kind of peace-pipe in order to restore the friendship.

Pliff and Plops push Plummy away from the minigolf course. He turns himself into many things in order to disrupt their game: as a ball with a mind of its own, as an unexpected hindrance and as a living hockey stick, which turns itself into a lasso. But, as ever, they become friends again and begin a fair match as a threesome.

Plops swallows a ball, gets terrible hiccoughs and has to be taken to hospital. Plummy and Pliff as doctor and nurse try to help him, but nothing works. Only when Plummy turns himself into a crane, picks Plops upside down, dangles and shakes him, does he manage to spit out the ball.

Plummy has just decorated a beautiful Christmas Tree, when Pliff and Plops suddenly start a snowball fight. Within moments there is a big mess. Plummy camouflages himself as 'Santa Claus' with a big bag full with Christmas presents. But before they get anything, Pliff and Plops have to tidy up and to decorate the tree again before the spirit of Christmas finally comes to the Plonsters.

Pliff and Plops trick Plummy and pinch his picnic basket, with which he is now making himself comfortable on the beach. Plummy gets everything back by transforming himself into different things - as a crab, seagull and sand worm. He finally manages to catch a big fish, which gets grilled on the beach as a reconciliation meal for the Plonsters.

Because Plummy accidentally swings his surfboard and hits them over the head, Pliff and Plops get in his way by turning themselves into a sand dune the size of a house, and a huge wave. But Plummy sails around them undeterred. After their spot of surfing, they all lie down in the sun and take the surfboard apart and use it as a beach towel!
