There is a new building in Treasure Town which has shops call Spinda's Drink Stand and Explore Recycle and Big Treasure. The building's name is Spinda's Cafe.
Spinda's Cafe is located near the exit of Treasure Town. It gives you access to the Unexplored Land once you get to a certain part of the game. In Spinda's Drink Stand, you can turn Apples, Seeds, and Berries into Drinks for a wee price. Drinks will have new effects once you drink them in Dungeons.
The other stall is a two-function stall owned by a Wynaut and its evolution, Wobbuffet. Explore Recycle is run by Wynaut. It allows you to trade excess Items that you have for other items. The quality of the Items increases with the more Items you exchange in so be sure to keep coming to the stall. The other stall that's run by Wobbuffet, the Big Treasure stall, has you enter lottery for a certain price... The prizes for this lottery vary so what you get will be random...
