This Sims 4 Halloween decor set contains a variety of spooky-themed decorations for your Sim’s home. These include glowing cauldrons, pumpkin clusters, candlelit lanterns, skull accents, and crow decor pieces that instantly transform any space into a haunted gathering. The “BOO” wall sign is my favorite piece in the collection. It’s cute yet still hauntingly creepy. Note that some of the decorations require specific stuff packs, e.g., the Candle in Pumpkin cage requires Celebration Stuff while the Cauldron requires Island Living.
Follow these steps to install Boo! – Spooky Soiree on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
Open your Sims 4 Mods folder. The default location is: Documents/Electronic Arts/The Sims 4/Mods
Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
Important: Always back up your save files before installing new mods. After Sims 4 updates, mods may need to be re-downloaded or updated by the creator.

Pro tip: If a mod stops working after a game update, check the creator's page for an updated version. Broken mods can cause the game to behave unexpectedly.
