The Tails and Paws detective agency received an urgent request for help. The message arrived all the way from the North Pole! The animal scientists from the research station are terrified! A mysterious villain is trying to disrupt their work and is always setting dangerous traps for them. And only a ghostly unicorn prevents him from gaining the upper hand. I, Woof Tail, the best detective in the world, am puzzled! Who is this criminal? And what is this ghostly unicorn? Everyone knows that unicorns don't exist! My partner Mina Moore and I are taking on a new investigation. Oh, how many surprises await us!
