In the beginning of the episode, D.W. and her friend Emily put on an array of protective gear because they have to go to the Tibbles' house for a play date. When they arrive at their mansion, the Tibbles open the door and shout into the girls' faces. Later, the Tibbles are playing rough, much to D.W. and Emily's shock and despair. That night, D.W. made a wish on a star which was really a helicopter to her dismay. The next day, D.W. and Emily saw Tommy without Timmy. Then they heard that Timmy is sick. Later, Tommy visited Timmy to bring him a get-well card from him and his classmates. Later as D.W. and Emily came over, they took off their protective gear because they were safe. Later, D.W., Emily, and Jane brought Tommy to the carnival to cheer him up, but it didn't work. So D.W. and Emily took turns being Tibbles for a day. A few days later, D.W. and Emily safely decide to quit. At the Tibbles' house, they were surprised to see Timmy at the door. Timmy explained he's better and that Tommy caught his sickness. He also thanked them for filling in for them and asked them if one of them wants to play biplane with him. D.W. volunteers, and the episode ends.
