Eh.  It’s another take on bedtime monsters, as the title indicates.  In this one we see a little boy playing monster before bed, and then wanting to sleep with his parents for fear of the monsters that may materialize.  Mom has little sympathy, and sure enough, a series of monsters present themselves, each declaring that they are afraid of some other monster (which is sure to be the next one to arrive), and crawling into bed with Arnold, until it is quite crowded.  The last monster says he’s scared of Arnolds, and so when Arnold declares his identity all the monsters scurry off to their corners and Arnold has his bed back to himself.  The most interesting page is at the end, when the illustration shows all the monsters lurking in the parts of the room where we can see what real items in the room inspired their births in Arnold’s imagination.  All around, it’s okay, but I wasn’t particularly wowed.
