Problem solving and storytelling

The video below features capuchin monkeys co-operating to solve the problem of opening a container with food inside and one monkey choosing to share the rewards of their co-operation with the other one.

Many stories are basically a case of a character wanting something, having to overcome a problem (or several) to get what they want, perhaps with the help of another character (or several), getting or not getting what they want and how their circumstances are changed following their attempt to solve the problem.
