Cocoon poem

It dangles from an elegant tree
The cocoon dangles near the sea 
It is as brown as rich dirt
Inside the caterpillar lays unhurt
Suddenly there’s a crack 
About the size of a cranberry 
Over the few days it gets bigger 
On an early morning alone came a digger 
And knocked the cocoon down 
Into the street of a nearby town
And the cocoon cracked and broke 
The newly formed butterfly got a fright
It was a beautiful butterfly
The tips of its wings were the colour of the sky
Its wings fluttered like excited children 
And flew away into the big wide world
