The Sims 4 Dives Into Bikini Bottom with New SpongeBob Kits
SpongeBob fans finally get their moment in The Sims 4. EA has announced the Bikini Bottom Bundle, a limited-time set that combines The Sims 4 SpongeBob’s House Kit and The Sims 4 SpongeBob Kids Room Kit with a few extra bonus items. With these kits you can build the famous pineapple house, set up a SpongeBob themed kids’ room and add a lot of small nautical details to your Sims’ homes.
The Bikini Bottom Bundle is available from December 4, 2025 and stays on sale until March 3, 2026. Besides the two kits, the bundle also includes three exclusive objects: The Flying Dutchman’s Jungle Gym, the Goofy Goober Guitar and the Conch Street Aquarium. It is a small package, but clearly made for players who enjoy playful, colourful builds and want their households to feel like they live one step away from Bikini Bottom.
SpongeBob’s House Kit – Build Your Own Pineapple
The first kit focuses on the iconic address 124 Conch Street. With SpongeBob’s House Kit you can recreate the pineapple house using dedicated walls, siding and roofing, topped with a Pineapple Topper. Floor tiles and wallpapers like Sturdy Steel Plating, Bamboo Block Print and Sun-Soaked Sand help to continue the theme into the interior.
The build details are surprisingly rich: a Steel Hatch front door, Port-of-Call Porthole Windows and a Brilliant Bubble Vent make the house feel like it really belongs under the sea. On the furniture side you get several recognisable pieces from the show, for example the Diver Helmet TV, the loud Foghorn Alarm, the Legendary Life Raft Chair, the “I’m Ready!” Single Bed, a barrel-style armchair, inflatable seating and a Krusty Krab inspired dining table. It is basically a small catalogue of items that let you tell very specific SpongeBob stories in your saves.
SpongeBob Kids Room Kit – For the Smallest Fans
The second kit, SpongeBob Kids Room Kit, turns a children’s bedroom into a fan space filled with character art and toys. There is a SpongeBob themed bed, a set of pineapple-inspired furniture (desk, activity table, nightstand, dresser and bookshelf), a clam-shaped task chair and many small decorative pieces like a Gary wall clock, a “Many Faces of Gary” lamp and colourful wall decals of SpongeBob and Patrick.
For playtime there is a Krusty Krab play set so kids can act out their own Krabby Patty stories, plus plushies of SpongeBob, Patrick and Sandy. Altogether it feels like a good match for family gameplay and for saves where one child is clearly the big SpongeBob fan in the household.
Extra Tie-In Items in the Deck the Palms Event
The release of the kits is also connected to the Deck the Palms holiday login event (December 16, 2025 – January 11, 2026). During this free in-game event players can unlock several SpongeBob-related items, including:
- a Krabby Patty Secret Recipe for your Sims’ cooking menu,
- a themed phone skin,
- and a sweatshirt with SpongeBob inspired colour variants.
So even if you are not sure yet about buying the full kits, it is still worth logging in a few times during the event and grabbing these smaller pieces for your collection.
Pricing and Platforms
The Sims 4 SpongeBob’s House Kit and The Sims 4 SpongeBob Kids Room Kit can both be bought separately for $6.99 USD each. The Bikini Bottom Bundle that includes both kits plus the three bonus objects is priced at $9.99 USD and is available until March 3, 2026.
The bundle and the standalone kits are available on PC via EA app, Mac (Origin), Epic Games Store, Steam, PlayStation 4/5 and Xbox One / Series X|S. As usual, you only need the free The Sims 4 base game with the latest updates to add them to your save.
If you enjoy more playful, themed content and do not mind your neighbourhood suddenly getting a pineapple neighbour, this SpongeBob crossover is a fun little corner of The Sims 4 universe to explore.
