Hattie didn’t start out being bad, but she soon realized that being good was not fun or exciting.  Other children admired Hattie, but their parents would not let them play with her.  Hattie was lonely, so she switched to being Hattie the Good.  Parents were happy, but the other children began to avoid her.  Hattie was lonely again.  When Hattie won a competition to find the “Best-Behaved Child Ever”, a funny feeling grew inside her.  When asked if there was anything she would like to say, she did a handstand and yelled “Underpants!” as loudly as she could.  Children rejoiced that Hattie the Bad was back (with a little bit of good) and Hattie was never lonely again.  Joe Berger’s energetic black-line illustrations complement the text wonderfully.  Pages with Bad Hattie are splashed with bold color.  When Hattie switches to Hattie the Good, he paints neatly with a sedate pink.
