WATCH OUT! A GIANT!
This is one of Carle's junkier gimmicks, with all sorts of peep holes through pages and trap doors that open, but these cutouts are not coordinated with the rudimentary story and many are not even coordinated with the other pictures they open onto. What goes on, in coarse, scribbled-over collages, is a sort of chase whereby two children grope their way through dungeon and tunnel and so on, to escape the giant who has caught them and plans to eat them. But it's not worth trying to follow, as the distractions overwhelm.
