Super fun and silly - a hippo trying to figure out what the spot on his backside is and everyone has an opinion. The book is great, until the ending. Ugh - a little too gross for me. I'll still probably work it into a preschool "silly" or "hippo" themed story time as some point and we'll talk about the disgusting ending. 
 [SPOILER ALERT]..... 
 The spot turns out to be a piece of gum a little boy has lost and he grabs it off the hippo's backside and pops it into his mouth. Gross!
