Judy Moody, Mood Martian

Summary

When it is "Backward Day," Judy must turn her usual sour mood upside down and be happy and nice for a change. On Backwards Day, Judy decides to change her mood to "cool-as-a-cucumber neat freak," and, surprisingly, this new mood hangs around for days, but soon her friends begin to question whether this "new" Judy is just an imposter.
