A urgent request for help came to the detective agency "tails and paws". The message arrived already from the North Pole! Beast-scientists from the research station are horrified! The mysterious villain tries to disrupt their work and always adjusts them with dangerous traps. And only a ghostly unicorn does not allow him to prevail. I, bang tail, the best detective in the world, is puzzled! Who is this criminal? And what kind of ghostly unicorn? Everyone knows that unicorns do not exist!
