The cast sing of a craft racing through space

When it lands on Earth out step some very strange creatures - the Bumblesnouts!

Almost immediately their ship is attacked by some very unpleasant characters 
until the Bumblesnouts tell them off.

Next along comes Mrs. Fizzy with her cleaner friends.  
With their aerosol cans and other harmful chemicals, they need sorting out.

Next on the scene are some hunters.  The Bumblesnouts are alarmed 
at the way they are killing all the animals of the forest.
