Starting at what is later revealed to be the westernmost of two southern entrances, the player is led on a winding path through many patches of grass. The tall trees cast an eternal shadow over the ground, but it is still possible to see. It is dark enough, however, that other travelers have had the misfortune to drop and lose their items on the ground. It is possible to find these without technological assistance, but the Itemfinder makes searching a great deal easier.
The Petalburg Woods are abundant with wild Pokémon. Many low-leveled Bug-type Pokémon make it their home and can commonly be encountered in tall grass, but there are rarer Pokémon here as well. Slakoth and Shroomish can only be found within the confines of the forest. These rare Pokémon are often sought by collectors in nearby Rustboro City.
Near the northern exit to Route 104, a pair of saplings block a forked path to the east. When HM01 (Cut) has been obtained, and the RustboroGym LeaderRoxanne has been defeated in battle, the bushes may be temporarily cleared. This allows access to the easternmost half of the forest.
The first time the player traverses the woods they travel north. On this trip, they encounter a Devon Corporation employee being attacked by a Grunt of Team MagmaROR/Team AquaSEAS, who requests assistance. Once the Grunt is defeated, the man will reward the player with a Great BallRSE or the Exp. ShareORAS, before making his way back to his company headquarters.
In Omega Ruby and Alpha Sapphire only, the Moss Rock is located here.
Trainers with a PokéNav by their names will be registered in the Trainer's Eyes or Match Call function after the first battle, and may have a rematch with the player with higher-level Pokémon.
Any POKéMON that appears even once
in a battle is awarded EXP Points.
To raise a weak POKéMON, put it at the
left of the team list.
As soon as a battle starts, switch it
out. It will earn EXP Points without
being exposed to any harm.
In addition to Hit Points [HP], POKéMON
have Power Points [PP] that are used to
make moves during battle.
If a POKéMON runs out of PP, it must be
taken to a POKéMON CENTER.
Petalburg Woods, referred to as Petalburg Forest in the anime, appeared over the course of several episodes. The dense forest is home to a wide array of wild Pokémon like Beedrill and Zigzagoon.
Its first appearance was in You Never Can Taillow, where Ash and his friends sat down to enjoy a break. However, they were interrupted by an angry horde of Taillow. During the chaos, Ash encountered Brock again, and he agreed to rejoin Ash on his journey through Hoenn. Thanks to Brock's advice, Ash caught one of the Taillow that attacked them, while Brock's cooking abilities were able to settle the rowdy Tiny Swallow Pokémon.
Ash stumbled upon a wild population of Treecko in Tree's a Crowd. Their current home, a large old tree, was close to death and ended up splitting in two. Fortunately, a seed appeared and Ash's newly caught Treecko planted it before leaving its community to look after the seed.
