Young (and old readers) will puzzle over this wordless picture book. Where is Mr. Crocodile going as he gets up, gets dressed, takes the Paris Metro.  There are double page spreads interspersed with multiple images per page (usually to show lots of action and business).  Some people notice him, others don't and there are other animal characters mingling with the human ones.  His final destination is fun and can spark some interesting discussions.   The soft pastel pictures with a blending of foreground and background add to the gentle joy of this very original story.
