-Excerpt from the book Goodbye Monsters
Meet Zimbobo

Zimbobo is a magical creature with supernatural powers that keep all of the monsters away.  All you have to do is place Zimbobo anywhere you believe there are monsters and Zimbobo will keep the scary monsters away.  We recommend placing Zimbobo under the bed or in the closet, but you know best where the monsters are hiding!  

Zimbobo has never seen a monster. Zimbobo's special power is sending out ultrasonic waves that scare monsters away.  

All Ben has to do is place Zimbobo anywhere he believes there are monsters!
