You will not believe the squishy, sticky, and incredibly sweet disaster that follows! When a colossal misunderstanding leads to thousands of marshmallows flying through the air, both towns are forced to deal with a towering, sugary mess. This delightfully funny story proves that sometimes a messy situation is exactly what people need to discover that sharing and friendship are the best solutions of all.
