My Crazy Alphabet Book

The other day, my friends and I were talking about how everyone knows what a Xylophone is.  I realised, of course, people know what a xylophone is because it's the X-word in all the kids' alphabet books.  A is apple, B is banana, C is cat, X is xylophone.

Then I remembered MY old alphabet book.

Here's the X page...

Look again...

Extra large mouse?!  That doesn't even start with X.  I think the reason I've kept this book for 15 years is because this page is so bonkers.
