In this fourth book, Ed goes to sign up for the bowling league, but accidentally signs up for a playwriting contest instead. Ed and his friends write a VERY wacky play that stars a hamburger, a moose, a ninja, and even a pirate mouse! While performing the play, Ed's powers as the Stranger make things in the Looniverse turn more than a little loony! Ed scrambles to stop the strangeness before it's too late.
