What does this monster have under his bed?

Bobo is a young monster who's afraid to sleep in his own bed.
He is sure there is a boy hiding beneath it - a boy with "pink
skin and orange fur on his head where his horns should be."
Bobo's older brother thinks he's a fraidy-cat, but his grandpa,
Boo-Dad, knows all about these fearful creatures. And Boo-Dad
knows exactly what to do to scare them away. But after being
afraid for so long, Bobo might just want to take matters into his
own paws and find out if the creature under his bed really is as
bad as he thinks.

This rambunctious story of a youngster overcoming anxiety and
limitations is set in a captivating otherworld that springs to life
in pictures full of enchantment and surprise.
