Never swap your dad with friends, because you might not get him back . . .
When a boy swaps his dad for two goldfish he does not really think through the consequences! After all, he is not the only person who can swap stuff. When he is told by his mother that he has to get his father back it is not so easily done. It seems that the father has a pretty high value and he has been traded by one child to the next, leaving a trail that the son has to follow.
Where will it all end?
