A mentally challenged man escapes from his tyrannical master and finds happiness when a poor family takes him in.

The inhabitants of the saltkråkan get it really hot on the ears when Malin and Peter is their first child-Skrållan! It will not be easy for such a confused and awkward grandpa, Uncle Melker to keep track of her. Scrap accommodates namely, as soon as she can-and Stina does not make it easier by selling the Scrap to the Vesterman for 25 cents.

Vesterman has found a young seal in his fishing nets in the outskirts of the archipelago. When he comes back to the Saltkråkan island he gives the seal to Tjorven, who names it Moses. Peter Malm, a visitor who works at the Zoological Institute in Uppsala, wants to buy the seal, but Tjorven says it's not for sale. Vesterman is in need of money and tries to get the seal back, to sell it to Peter. The children have to hide the seal, so he won't find it. Pelle's rabbit Jocke and one of Söderman's lambs are found bitten to death. The dog Båtsman is accused of those evil deeds, which means that Tjorven's father has to shoot her dog. In the last minute Söderman finds out that a fox is the perpetrator. Peter Malm says he won't buy the seal. Vesterman is disappointed and the seal stays with the children.

Tjorven and the other children at Saltkråkan have received a play day in a gift. Uncel Melker will find himself ending up in the lake several times. The kids also have found an old ship that will be named Albertina. They divide themselves into two pirate gangs and fights about The wishing stone Mysak.
