'Garton the Ghastly, the goblin king, is furious with the fairies for foiling his wicked plans for diamond mines and central heating, and plots revenge. Using the stolen Plant Spell Book, and a stolen wand from a flower fairy, he makes a spell to cause all the fairies to lose their voices.
'Garton is also creating problems for the triggles, small furry creatures who eat mud and live under the Glittering Plains. They dig up pieces of stones and gems to make the plains glitter, but Garton, greedy as ever, has decided the jewels would be better off in his possession.
'He poisons the plains and tricks the triggles into thinking it was the fairies, and convinces them to give him all the jewels. The triggles, who swell and explode when they are frightened, shower the flower fairies with mud. The bedraggled flower fairies need the fairies help, but their voices are lost so they can t communicate!
'Cedar knows a spell that will restore their voices, involving a rare purple rose that can be found on a sapphire. Sadly, because the triggles are giving Garton all the jewels, there are hardly any sapphires left, but luckily, right on the edge of the Glittering Plains, Cedar spies one last glittering gem and a deep purple rose the potion is made and the fairies voices return.
