Big Bird doesn't see Grover hiding behind the couch or Bert concealed in a tire, but children will be sure to spot them behind the die-cut peek-a-boo holes

(Little Brown & Co, April 1, 1994)
Small children peek through die-cut holes to see their favorite animals, imitate their silly nonsense sounds, and learn about shapes and colors. By the author of Fish and Flamingo.
Children try to guess what things are peeping through the die-cut holes on each page and, in turning, are surprised to find that a snake is really a piece of rope and that the sun is really a flashlight.
