The naughtiest unicorn and the firework festival

"It's time for some firework festival fun at Unicorn School! But there's only one problem... the fireworks are missing! But - this being Unicorn School - the fireworks are very special and magical, created by mysterious creatures who live behind the Fearsome Forest. It's time for Mira, Dave and the gang to go on an adventure, find out what is going on and make sure that the sparkling, colourful, fizzing firework fun is returned to the festival with a BANG!"--Publisher's description.
