The Boom-Boom Book

According to E - for reasons best known to herself* - and with apologies to Eric Carle. 

In the light of the moon, a little green egg lay on a leaf.
One Sunday morning the warm sun came up and - pop! - out of the egg came a tiny and very hungry boom-boom.
He started to look for some food.
On Monday the boom-boom ate through one apple. But the boom-boom was still hungry.
On Tuesday the boom-boom ate through two pears, but the boom-boom was still hungry.
On Wednesday the boom-boom ate through three plums, but the boom-boom was still hungry.
On Thursday the boom-boom ate through four strawberries, but the boom-boom was still hungry.
On Friday the boom-boom ate through five oranges, but the boom-boom was still hungry.
On Saturday the boom-boom ate one piece of choc-o-late cake, one ice-cream cone, one pickle, one slice of Swiss cheese, one slice of sam-a-li, one lollipop, one piece of cherry pie, one sausage, one cupcake and one slice of watermelon. That night the boom-boom had a stomachache!
The next day was Sunday again. The boom-boom ate one nice green leaf and after that he felt much better.
Now the boom-boom wasn't hungry anymore - and he wasn't a little boom-boom anymore. He was a BIG, FAT boom-boom.
He built a small house, called a cocoon, around himself. He stayed inside for more than two weeks. Then he nibbled a hole in the cocoon, pushed his way out and...
the boom-boom was a beautiful butterfly.

* but which are apparently very funny. She now walks around with the book saying 'I call this the boom-boom book!' Quite possibly the cutest thing ever.
