The Jungle Kingdom Book 2 Volume 3 Hammer

As Stud wanders the Jungle Kingdom looking for a way back home, he again encounters Brymm, who has been searching for someone to help her save her kingdom.

She continuously asks Stud for help, but he refuses, hoping to get back home as soon as possible, before his father returns. But after his bag and the Kingdom Maps are stolen by the animal warriors working for Brutus Elephanté, Stud just might have to reconsider if he expects Brymm to help him get them back. Will Stud be able to retrieve his bag before it's given to King Elephanté? Will Brymm find the help she needs to save her kingdom?

Hammer
Stud is a 14-year-old boy with the unusual ability to turn his hands into hammers. With a father who often abandons him to go on expeditions, Stud fends for himself while trying to achieve the goal his father has told him is the most important in life: to make a true friend. Unfortunately, the other kids in his town shun him for being weird, so he goes on his own adventures and finds true friends along the way.
