What’s it all about?

Happy has noticed a tiny fruit fly on his apple, and the Squirrels are amazed by how small it is. The fly tells them that there are things even smaller than him! But what?

Luckily Duggee has his Size Badge. He teaches the Squirrels that some things are so small that you can’t even see them. They’re called atoms. Combined, these atoms make molecules, which in turn join to make cells, the fabric that makes up every living thing. Amazing!

This Is The Episode Where…

  • The Squirrels discover that things can be wide, long, thin or small
  • The Squirrels line things up in order of size
  • A small piece of dust is the smallest in the line up
  • A huge rocket ship is the biggest

A blue whale! The biggest living animal on Earth“
