The play (which may be this one? I don't think so though) begins with Little Red Writing Hood, who has the script to her own story and others, and she uses her pencil to make changes to the script. When the wolf comes, she doesn't want to be eaten, so she changes him into a ballerina to make him harmless (although, ballet dancers are STRONG and have incredible endurance, so I wouldn't necessarily choose that but, you know, fourth grade play). When Goldilocks is being chased by the bears, Writing Hood changes her into a bear cub and the family adopts her. Writing Hood introduces Prince Charming to Little Miss Muffett, etc.
At first I was thinking, all right, a play that encourages empowerment and learning from other people's mistakes, and hopefully inspires a love of writing and the ability to create your own stories, that's great. But then in the second half, Writing Hood's changes have begun to get out of hand. Goldilocks doesn't want to be a bear any more, Charming wants to take Miss Muffett to the ball so now Cinderella is all alone, and none of the solutions were as simple as she thought-and now she's run out of eraser. Enter the FBI-the Fairy tale Believers Incorporated (haha). They take over and change the script back to what it was supposed to be, because "fairy tales shouldn't be changed." When Writing Hood protests that she doesn't want to be eaten by the wolf, the FBI reminds her that she knows she'll get rescued.

I just think the conclusion is very telling. Many people have this idea that fairy tales are sacred and don't realize that the versions we now know as "traditional" underwent many, many changes to become that way. With all of these new versions of fairy tales coming out, it can be so tricky to reinterpret the tales in a way that isn't ignorant of the tale's history or other modern versions. People grew up with traditional tales (whether Grimm or Disney or probably a combination thereof) and some people are resistant to the idea of changing these stories that resonated with us so much in childhood.
Being an elementary school play we shouldn't read into it too much, but it still reflects how people interact with fairy tales, and to any kid who is ever in that play, the story will probably stick with them for a while.
