Book Description: Five animal friends set out in a raft, and there's plenty of space. Then a voice pleads "Move over! Move over! Make room for me." So they all move over--and no one falls out. But then another pal begs to come in. And another. Yet even with Hippo aboard, all is well. But sometimes it's the tiniest creature that makes the biggest difference of all. Amusing speech balloons add to the fun of this humorous cumulative story.
