Goldenrod Tunnel

The Goldenrod Tunnel (Japanese: コガネちかつうろ Kogane Tunnel), known as the Underground (Japanese: ちかつうろ Underground Path) in Generation II, is a shopping district stretching below Goldenrod City. The shops that are open in the Tunnel depend on the days of the week and, in some cases, the time of day.

Shops
Goldenrod Tunnel contains a barber shop, a Bargain Shop that sells valuable items, and an Herb Shop. Each shop has set hours of operation and all three are never open at the same time.

Pokémon Salon
Once a day when the shop is open, the player may have one of the brothers give a Pokémon a haircut. This increases the Pokémon's friendship. In HeartGold and SoulSilver, it also raises the Pokémon's stat.

The younger of the Haircut brothers is cheaper at 300, but his service is often less satisfactory. However, the younger brother has a chance of occasionally increasing a Pokémon's friendship to a greater degree than the older brother is capable of. The older brother is more reliable but more expensive at 500.

Bargain shop
On Monday mornings, a man sells a set of valuable items for a discount. Each item can only be purchased once per week. The man can still sell his items on other mornings provided the player has saved in front of him and does not walk away and remove him from the screen. The prices here are approximately 10% cheaper than the items' normal sell prices.

Goldenrod Department Store basement
The Goldenrod Department Store's basement opens up onto the Goldenrod Tunnel. Although the basement is accessible from the main store right from the start, the back entrance is initially occupied by Team Rocket and cannot be accessed until later. Petrel hides the Goldenrod Radio Tower Director here while he impersonates him but will give the player the Basement Key upon being defeated. Inside, there are s and to  and a series of switches to turn ON/OFF in order to navigate through the basement completely.

Some rare items can be found in this section of the Department Store's basement.

Photo booth
In, there is a photo booth at the northern end of the Tunnel. s can dress up and photograph their own using Accessories, and a man offers to take photographs of Trainers with their on-hand party. This photo opportunity is unique, as undefineds can wear themselves a costume.

During Team Rocket's invasion of the Goldenrod Radio Tower, the player must wear this uniform as a disguise to enter the Radio Tower. They will not in this costume nor can they (legitimately) leave Goldenrod City while wearing it.

Photo gallery
The saved photo of a dressed-up from the photo booth is displayed in the photo gallery. In addition, photos from up to ten undefineds that have mixed records with will also have their photos displayed here.

A appears in the photo gallery who runs an Accessory drawing. The player can apply for 100, having the chance to win a random Accessory.
