If you've got a bit of time and want to find out a little more about worms have a look at this little video from the Natural History Museum. Learn to love earth worms...
The Earthworm appears in one of my favourite books, James and the Giant Peach. This video is a little clip from the cartoon of this book. I hope you enjoy this song:
"'I am not a slimy beast,' the Earthworm said. 'I am a useful and much loved creature. Ask any gardener you like.'" - James and the Giant Peach
He is a pretty gloomy creature - as the Ladybird tells James, "'He hates to be happy. He is only happy when he is gloomy. Now isn't that odd? But then, I suppose just being an Earthworm is enough to make a person pretty gloomy, don't you agree?'"
James is quick to point out the Earthworm's good points: "'He would be absolutely grand for digging subway tunnels and for making you a sewer.'"
