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

Gremlin’s Shoes is the fifth book in award-winning author Ellen Potter’s charming Big Foot and Little Foot chapter book series about the adventures of a human boy and a young Sasquatch—with illustrations by award-winning artist Felicita Sala.
 
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!
