Don't go out in the woods today. Mario is spending winter break with his neighbours, Todd and Jewel, on their family vacation to Vermont. He is excited to see snow for the first time and meet his friends' beloved grandparents. But Todd and Jewel's grandparents turn out to be a little odd. They love telling tall tales of goblins, elves and trolls. When Mario spots a blur of green fur in the garden, he wonders if the stories could be real. He's determined to find out what's going on, but the truth might be more dangerous than fiction!
