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.
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.
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 Beauty 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 Mondaymornings, 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.
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 BasementKey upon being defeated. Inside, there are Team Rocket Grunts and Silver to battle 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.
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 battle in this costume nor can they (legitimately) leave Goldenrod City while wearing it.
Photo gallery
The saved photo of a dressed-up Pokémon from the photo booth is displayed in the photo gallery. In addition, photos from up to ten players that have mixed records with will also have their photos displayed here.
A Hiker appears in the photo gallery who runs an Accessory drawing. The player can apply for $100, having the chance to win a random Accessory.
