Get Well, Good Knight (Penguin Young Readers, L3)

The much-heralded Good Knight is back-only this time his three little dragon friends are sick in bed.  Their scaly foreheads are hot and their noses are drip-drip-dripping.  They feel awful.  The Good Knight comes to the rescue again!  He brings them some slimy, grimy soup from the wizard to make them feel better.  But the dragons wont touch it.  What is a Good Knight to do?
