Oh , how fun! Okay, the little mouse in this book is trying to find a friend. He's a little fellow looking up at just the tail of an animal and asking the question, 'Do you want to be my friend?' Now, can you tell by looking at the tail what animal is waiting on the next page? Hmmm. That looks like a horse's tail to me'turn the page and it IS a horse's tail. Oh, now whose tail is that? Will that animal be the mouse's friend? Keep turning. This is great for little listeners who need to interact with the book. All along the way, there is a pretty green line. Is that the path? Or perhaps it's something else?
