The Pigs Went Marching Out is my alltime favorite childrens book. It's fun to read because it rhymes. It would be a good bedtime story because you can read it pretty fast. The story is about a pig that leads all his fellow pigs out of the farm because he is tired of it. They go to a fair and have a lot of fun. Then somehow there is a blizzard and they hide in a cave and there is a grizzly bear in there. They are about to die but the farmer and his dog rescue them.
