The Unicorn Emergency

Back from a trip to Asgard, Demon, the official Beast Keeper of Mount Olympus, finds himself facing a fresh wave of trouble: a grumbling volcano monster and a herd of unicorns that are mysteriously ill. A cryptic note reading "Unicorn Emergency!" is the only clue he has to the source of the unicorns' ailment. With time running out, Demon must solve the puzzle, manage the erupting beast, and restore the unicorns before the crisis worsens.
