A borrowed body
Spencer lands in detention with Fridge, Bethany and Martha and picks Bravestone on the console. In the game he gets Dwayne Johnson's body, three lives and no weaknesses.
Spencer got detention for doing homework for Fridge, the friend who drifted away from him. Inside the game the roles flip: Spencer is the giant, and Fridge is the little guy carrying the weapons.
The shock doesn't last. Guide Nigel lays out the mission: return the Jaguar's Eye to the giant statue. The villain Van Pelt stole it and now controls the jungle's animals.
