A Different Kind of Goblin 

Glib, the evil Globlin hates happiness! He will stop at nothing to make all the creatures in Cuchavira miserable. He steals all the colour from the Elfins, kidnaps Fern the Fairy princess and destroys the Pixies village. But when fire rages through the forest, Glib reluctantly must ask for help. Can the Rainbow Girls and their Uncles Moonbow and Fogbow stop the fire from spreading and restore peace and harmony to Cuchavira once more?
