Pokémon Mystery Dungeon: Blue Rescue Team Tips

Good Place For Oran Berries
As we all know, Oran Berries are incredibly useful, but you have to either find or buy them. They're rarely ever in stock and are totally overpriced. Every now and then there will be one lying around, but as you progress through the game they become less and less common. A great place to find a lot of Oran Berries is in Waterfall Pond. There's more than you'll know what to do with just in a few trips. Waterfall Pond is also very short, so you can go over and over in preparation for a really long or tough cave.

Waterfall Pond is only available after you beat the storyline, and requires a Pokémon that knows Waterfall or the Waterfall Hidden Machine (which can be found in the Solar Cave).
