Here's another good one!!! I'm the Biggest Thing in the Ocean by Kevin Sherry is a simply wonderful book that we've used successfully in Toddler Storytime and regular Story Hour. It is about a squid that thinks he is the biggest thing in the ocean - he compares himself to lots of fun creatures and still believes he is the largest until he meets Mr. Whale!!!! And what ensues is GREAT FUN!!!! You won't be disappointed!!
