What is a June box? It's a jail for toys. Things that go into the box don't come out until the end of the school year.  So when the substitute teacher sees Harry playing with a pink origami pig, into the June box it goes. The problem is that Song Lee spent hours making this pig, which was supposed to be a birthday present for her grandmother. Song Lee decides there's only one thing to do: stage a prison break! Now Harry, Doug, and the rest of Room 3B have to work together -- before they all wind up in horrible trouble.
