The Gremlin's Shoes (Big Foot and Little Foot #5)

In the fifth book in this charming chapter book series, a human boy and a young Sasquatch set off on an eventful treasure hunt through the North Woods. 

Hugo and Boone were having a bad case of Nothing-to-do-itis: they have free time, but can't think of a single thing to do! Finally, they decide to head to Uncle Figgy's Toy Store, where they discover the legendary Mad Marvin presenting his new invention: the Marvelous Monster Magnet! The only problem is the toy costs 25 nubbins--a huge sum! Hugo and Boone set off on an adventure to earn the money, a journey that leads them to a treasure hunt through the woods. As always, the friends will find much more than they expected!
