The Laboratory
The Laboratory enables various resource conversions and is also rewarded by completing the new campaign quest chain; this reward is unique in that it does not count towards the shop limit of 1 per player. Additional Laboratories will increase the production speed of these conversions.
It costs 3,999 Pumpkins and you cannot trade it or send it as a gift.
The Haunted Mansion
The Haunted Mansion increases your population limit by 145, while also having some other spooky surprises when you interact with it. It's limited to 3 per player.
It costs 2,450 Pumpkins and can be traded, but it's not giftable.
PUMPKIN CEMETERIES
Production: Each Pumpkin cemetery produces event resources (Pumpkins) over time
Limit: 3 per player and version = 9 buildings (former acquisitions don't count)
You can build them on your island: not only do they provide Pumpkins, but they also contribute to the Halloween mood!
The Pumpkin cemeteries can only be refilled with "Pumpkin refillers". If you're wondering how you can get those precious refillers, you should play adventures: not all of them offer Pumpkin refillers, but most of them do. You can find the complete list in the in-game Event window.
There's another thing that can happen to your Pumpkin cemeteries: they can deplete. If that is the case, you can purchase Fertilizer from the in-game merchant to revive them. It costs 75 Pumpkins and it revives the depleted cemetery with 10 Pumpkins. This might look like a bad deal at first, but you will be able to use refillers and buffs again on a restored cemetery.

Common version: Costs 150 marble and 200 hardwood planks
Noble version: Costs 10 granite and 25 exotic wood planks
