Simply, they are white because they eat only white food, such as mashed potatoes, milk, white bread, sugar cookies, vanilla ice cream and more. My boys added "marshmallows, cheese" and more.
After mommy leaves, they of course adventure on their own and eat broccoli, blueberries, strawberries, orange juice (This ghost thought "drinking" was safer than eating.) and chocolate chip cookies. Not sure if you can see, but the last one had "chocolate chips... all over.
Mom comes back and says, "I know what you have been doing! So you will all have a glass of milk and go right to bed." In the morning, when they woke up, they were all white again! (Don't you love the ending.) Check out the Time for Play blog (click on the name) for the complete story.
I am crazy about this because each student made their own set of the puppets. They are "reversible" and so simple. I did the first show and made a big deal about setting up the stage by covering a table with a sheet. This led to a wonderful discussion on how they could do it at home with chairs... and more. We are taking turns each day to tell it again. I love that you can change whatever they eat, just so long as the color matches. The boys totally get it and we have had great success. I sure hope you try it. Let me know if you do!
