Dee tries to ignore her homesickness so she can celebrate Oz-tastic Day — the happiest day of the year. But the gloomy balloon-y knows her real feelings.

While helping with emergencies all over Oz, Dee learns the hard way that she needs to rest to be her best — especially if she wants to stop Miss Ruby.
