Our heroes come across an old-fashioned robot planting seeds in a wasteland, and its protector, a powerful Chesnaught! They meet the inventor’s grandson and learn about Robon the robot’s mission to regrow the forest that used to cover the area. But so far nothing has worked, and Robon is starting to wear out.
Clemont does some repairs to get Robon back in top shape, and all the Pokémon work together to find an underground water source—but it’s blocked by an enormous rock. Robon drills through the rock to release a gushing spring, and as our heroes head toward Snowbelle City, it watches over the first signs of new growth!
