Have you ever read your kid that potty-training book, "Everyone Poops" and gone crazy at the page that says, "What does whale poop look like?" because you have to keep saying over and over to your wide-eyed toddler, "I don't know, honey. Mommy doesn't know what whale poop looks like, either." You're the Mom. You're supposed to know everything.
So, here you go ... a great pic with a great answer ... and you can even show junior if you want to. I showed my boys, and they LOVED it! Liam was demanding an answer, so we finally decided to find out once and for all! Accompanying article is quite informative too and includes additional pics, but this is really the best one. http://carlifrenneman.hubpages.com/hub/This-Is-What-Whale-Poo-Looks-Like
