As a little kid, I enjoyed popup books. The thrill of turning the page and being surprised by an elephant, a tree, or a flying trapeze was too much for me to resist! There's a wonderful connection that a child makes with something that literally springs off the page.
Why, then, did someone think THIS was a good idea???
I have no interest in turning the page and seeing a big hairy spider jumping out at me! Or, worse yet, a clown! Ack!! That would send me to the psych ward!!
This is little better!
Imagine, a gaggle of clowns (or is it a pod? a flock?) popping out into your face? Or an image of you naked in the middle of the office! Or a long, dark hallway with too many shadows and too many doors. Or ... whatever your worst nightmare entails (I expect details in the comments, people!! Nightmares and phobias!) This book is unnecessary, and like the one above it, very likely to cause permanent psychological trauma.
Then there's this one.
This one, I have to say, has potential.
