So the very hungry caterpillar ate through a whole bunch of crap, got a tummy ache, ate a leaf, and felt much better.
He was no longer hungry or skinny.
*this is also the reader's digest condensed version.
He built a house, called a cocoon (or tatoon in 2-year-old chatanese), around himself.
He stayed inside for almost 2 weeks, then fell off the door.
The nice people use wood glue to glue him to paper and hang him up via the internet.
You could see the beautiful butterfly forming in the cocoon.
Then he nibbled a hole, pushed his way out, and...
he fell to the ground and died.
Then the little boy picked him up and announced "dead butterfly" like it was the best thing in the world.
Until the Mommy made him throw it in the grass.
