If they lose that zing, and they just won't swing,
then the problem falls in your lap.
When your folks are square, then you must prepare.
What are you gonna prepare?
The parent trap!The kids are busy playing with each other, then one day a tremor goes through their innocent world: the parents of the two children are engaged in a feud! The group of friends have been ordered not to talk to each other, even to actively hate each other! It's obvious that their parents are holding the Idiot Ball and it's up to the kids to sort it out. Maybe they run away, forcing the parents to put everything aside to find them. Maybe they resolve the argument by using their Disney exact child logic and showing the adults just how silly their fight is. Either way, by the end of the episode/film, the children have resolved their parents' problems and the status quo is restored. Common in Nickelodeon series as a Recycled Script, but a more romantic version can be seen in Romeo and Juliet, thus making it Older Than Steam.
