Well apparently an elephant produces a mind blowing pongy 20 kilos of dung a day! How Much Poo Does an Elephant Do? is another book by Mitchell Symons that has lots of quirky, weird and wonderful trivia for 
you. I found this one fascinating: in India the term “man-eating” is only applied to tigers that have killed three or more people. Man-eating tigers are usually too old to capture wild animals. Isn’t that wild or what! So check out this book. If you like it then also try other books by the same author How to Avoid a Wombat’s Bum and Why Eating Bogeys is Good for You.
