It’s cute.  Small children will relate to Tiny Rabbit’s wish to grow as big and powerful as all the things around him.  But as time passes he only grows a little bit, but he does grow two powerful ears, which he comes to appreciate (along with his small size) when they help him hear the approach of the huge hungry lion and escape down his tiny hidden den.  A good tool for opening a discussion about learning to appreciate ourselves just as we are.
