If your apartment-room objective is Brittany's Pen Pals task, the girl you need is Carla in Room 8 of Greystone Estates. The important route is Room 7, the Grave Warden, and its Sledgehammer, which clears the rubble blocking your way forward. Ghost tentacles near Room 9 are a separate obstacle removed with a Cleansing Bomb.
The search phrase can also refer to other apartment encounters. This route is specifically for Carla and Pen Pals. Artwork for Abigail and the Apartment 4 Flesh Girl encounter have different objectives and do not need to be completed as substitutes for reaching Carla.
Start Pen Pals with Brittany
Talk to Brittany and establish that Carla is her missing pen pal. The destination is Room 8, but locating the number does not remove the obstacles between you and the room. Treat the journey as a route through the building rather than a simple walk straight to Carla's door.
Brittany also explains why helping Carla matters: she can arrange for her father's rare Bean Seeds to be stocked by Crawford. That is the promised outcome connected to this request. It does not turn every locked Greystone apartment into a required quest stage.
If your journal instead names Abigail and a painting, use the artist and Artwork for Abigail guide. Keep the recipient, requested action, and room destination together so you do not combine two unrelated quests into one route.
Prepare for the Greystone obstacles
A Cleansing Bomb is useful for the ghost tentacles around the Room 9 section. Bring one if you already have access to it. The heavy rubble needs the Sledgehammer obtained inside the building, so carrying an ordinary mining tool does not supply the required answer to that barrier.
The sewer-house and sector guide helps identify the Greystone connection if your difficulty is reaching the apartments through the underground network. Once in Greystone, use room numbers to orient the search. The useful sequence below follows the Pen Pals obstacles rather than a complete clear of every apartment.
Separate the blockers around Room 9
There are two visually different problems around Room 9: ghost tentacles and heavy debris. Both interrupt movement, but they require different actions. Read the interaction and identify which one is stopping your current route before using an item.
| Obstacle | Required answer | Important limit |
|---|---|---|
| Ghost tentacles | Cleansing Bomb | A different obstacle from the rubble |
| Heavy rubble | Sledgehammer from the Grave Warden | The hammer breaks when used on the debris |
| Gatis door | Gatis alignment | Not established as a requirement for the Carla route |
Use the Cleansing Bomb on the ghost growth when that is the blocked passage you need to clear. Keep the rubble in mind as a return destination after obtaining the hammer. The building's Gatis door can remain a separate objective rather than a reason to stop Pen Pals immediately.
Open Room 7 and defeat the Grave Warden
Find the Room 7 Key while progressing through the apartments, then use it to open Room 7. The key is reported along the route through the apartment enemies; a guaranteed named enemy drop is not established here. Do not replace the Room 7 Key with another room's key solely because both appear in the same building.
Room 7 contains the Grave Warden. Its useful combat detail is a weakness to Curse damage, while its attacks deal Insight damage. Curse-capable attacks are therefore a sensible choice if available, but the required result is winning the encounter and obtaining the tool.
After the fight, collect the Sledgehammer from the remains. Do not leave the room assuming the tool was automatically added if you have not checked the encounter's pickups. It is the item that resolves the rubble obstacle further along the route.
Break the rubble with the Sledgehammer
Take the Sledgehammer back to the heavy debris near the blocked section. Interact with that obstruction and use the hammer there. The rubble clears, and the Sledgehammer breaks in the process.
This is a single-use progression action, not a permanent pickaxe or axe upgrade. The broken hammer afterward is consistent with clearing this barrier. You do not need to preserve it as a long-term tool instead of opening the route to Room 8.
If the path is still blocked, identify what remains. Ghost tentacles still call for the Cleansing Bomb; a Gatis-only door is an alignment issue. Neither is evidence that the hammer should be used on every remaining obstruction in the building.
Reach Carla in Room 8
Continue through the newly opened route and enter Room 8. Carla is alive, and the missing letters are explained by her locked door. Talk to her; she agrees to write to Brittany again.
That conversation is the reason you came to Greystone for Pen Pals. Return to Brittany to follow up on her request and the promised Bean Seeds arrangement. The available details do not establish an additional hidden Pen Pals objective elsewhere in the building.
Apartment 4 and the basement laundry encounter are separate combat destinations. If you are pursuing the Apartment 4 encounter, use the Flesh Girl guide. Clearing those fights is not a replacement for speaking to Carla.
