Welcome to Hoenn like you’ve never seen it before! Professor Maple, the local Pokémon Professor in Littleroot Town, will welcome you to the world of Pokemon Grass Jewel. He is aided by his colleague Professor Pine’s son, Brendan, or daughter, May. This helper will become both your buddy and your adversary. When you encounter the professor, he is being pursued by a wild Zigzagoon and requests you to assist him in defeating it. As a result, he will give you the Pokémon you used in battle, enlist your assistance in working on the Pokédex, and put an end to a group of extremists known as Team Dream.
