The Jungle Kingdom, Book 1

Our hero Stud has teleported to the Jungle Kingdom.
Stud wants to focus on getting home, but after his bag and the Kingdom Maps are stolen, he fears he'll be lost forever. Realizing he can't get them back by himself, he enlists help from Brymm, a familiar ally with mysterious powers, who has a strange request--she needs help saving her kingdom in the future.
Brutus Elephanté, the Jungle King, will stop at nothing to gain the Kingdom Maps. His throne challenged, he sends his elite gorilla squad to intercept Stud and steal the maps.
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.
