What I would do for entertainment if my family was stranded on a deserted island is play tag or something like that. We might even make up a game. Maybe we could make up a game like you have to make up an opsticle course, and whoever does it the fastest wins. You could have a running part, a climbing part, a part where you throw rocks at something, and maybe even a part where you have to pick all the plants that you can find. The last thing that could be in that is running to the finish line. This is what I would do if my family and I were stranded on a deserted island.
