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 its blocked by an enormous rock. Ash and the gang: Ahh!
