Adult coloring books are so hot right now. We have to admit we own a book or five ourselves. There is something very zen about breaking out your deluxe 96 pack of crayons and coloring your feelings out. Now you can indulge in a bit of nostalgia at the same time! The “Harry Potter Magical Creatures” coloring book was released just yesterday, allowing Muggles everywhere to bring to life mandrakes, hippogriffs and much more in the way they always imagined them. The upcoming movie, “Fantastic Beasts and Where to Find Them,” is still several months away – hopefully this will hold you over until the magic hits the big screen once again.
