East of Doxy Marigold is a Hotshot Trainer guarding an entrance to an alleyway. After defeating him, he will allow you to pass, where you can find more trainers to battle, some Pokémon to catch, and a Super Potion. During Thunderstorm, a Joltik or Tynamo will appear here.
North of the Name Rater is a hotel owned by Mr. Seacrest. Seacrest has a beautiful garden in the back, but out of concern for its well-being, he requires trainers to battle him before passing through. Although accessible from Lower Peridot Ward, it's counted as part of Peridot Ward.
Southeast of the house of the fisherman who gave you an Old Rod is another fisherman who has an aquarium in his house. Like Mr. Seacrest, he requires a battle before letting you in. He has a level 10 Goldeen
After the restoration project has begun. The old man who owned a private garden is helping by spreading his collection of plants for new parks. Due to his incompetent friend, the mulch is spread across the Obsidia, Beryl, Lapis, and lower Peridot wards. If you retrieve them, he will reward you a Venusaurite and an Insect plate.Later, talk to the construction worker next to him and he will give you a Decidium-Z
North of the first entrance from the Opal Ward is a man asking for money. After giving three payments of 50, he will leave and let you pass through to a house holding either a traumatized Espurr or Minccino. If you have PokeSnax in your bag, the Pokémon will join your party.
A Teddiursa will appear in the streets during daytime when the weather is clear, and flee upon interaction, reappearing in another place. This encounter spans across both Peridot Ward and Lower Peridot Ward. Some older episodes have a bug where Teddiursa can glitch out this was patched in episode 18.2.
Kricketot cannot be obtained here after beating Julia's Gym
In the hotel next to the entrance to the underground Railnet, a girl is concerned about her Kricketot's ill state. The Bug gym leader Shelly is called in to look it over, and she declares that it isn't sick, it's just extremely lonely. As its current owner cannot give it the attention it needs, the two suggest the player look after it instead. If refused, Shelly will take it instead.
Whismur cannot be obtained here after beating Julia's Gym
Just past Casanova Darin is a dumpster that holds a Gulpin, as well as a house that holds a Whismur. The Whismur will appear only if you have a PokeSnax in your bag, and will react to it, but unlike the Espurr, it will attack, so it must be caught in-battle rather than be received.
Numel cannot be obtained here before beating Julia's Gym
During rain or a thunderstorm, a Numel will be outside the train station. If you have PokeSnax in your bag, the Numel will be attracted to it. It will know one of four possible Egg Moves: Body Slam, Growth, Iron Head or Stockpile.
After defeating Julia, return to the train station and speak with the man nearby, who has begun his search for a new home. Return to the house that had held a Whismur, where the landlord has returned. He asks you to send the man in, and after returning to tell the new renter this, the man shortly moves in. He gives you his old Onix as thanks.
