Grammy sends Josh a model rocket, which goes off accidentally and burns down the neighbor son's tree house. A true accident. Josh, Drake and Megan are all tasked with rebuilding the tree house, which causes Megan to miss a birthday party for her friend Janie. Neither Josh or Drake admit it wasn't Megan's fault (which it wasn't), but she gets payback when the boys seal themselves in the new tree house before cutting open a doorway, slowly going hungry while missing a double date with twins.
