It's the SPOOKIEST time of the year at Unicorn School! Mira and Dave the naughtiest unicorn are looking forward to dressing up for trick-or-treating, pumpkin carving and apple bobbing (well, doughnut bobbing for Dave).

Can they get to the bottom of what's going on, or are they in for a SERIOUSLY SPOOKY SURPRISE?
