Pokémon Ruby and Sapphire/Route 116



Follow the Aqua/Magma Grunt here to reach Route 116, which introduces you to new Pokémon to both find and fight.

The Route splits in two to go around a small grove of trees, with tall grass covering the way. Go down the Southern path for now, as there's only tall grass and a trainer up North, while down here is more tall grass, another trainer, and an item.

Heading East after the grove will result in the player finding yet more tall grass, and another trainer. Continue down the route to find a two chances for a double battle, between 3 trainers.

After dispatching the trainers, continue onwards to find a house full of miners, an entrance to Rusturf Tunnel, and an old man, along with an area accessible by Cut and an item. Talking to the man will reveal that his pet, Peeko, has been taken hostage by the Team Grunt inside the tunnel! Enter it to continue the storyline.

Who keeps putting up these fake trees?
The cut-accesible are contains a couple of trainers, some items, and a berry patch. It can also be used to bypass the Route's tall grass patches when travelling from Rusturf Tunnel to Rustboro City.

Emerald-only Secrets
After defeating the Elite Four and becoming the Champion, the Legendary Pokémon and  will retreat to the Terra and Marine caves, respectively. From there, you can catch them. However, only one of the caves is accessible at a time, and their locations rotate. If you don't catch, say, Kyogre before it moves, then Groudon will appear instead. If you do end up catching Kyogre, then Groudon's Terra Cave will always appear (Marine Cave will be locked away forever after this). One of the locations for Terra Cave is on Route 116, past the entrance to Rusturf Tunnel.
