The Sims 4 might be packed with bugs, DLC, and questionable monetization—but it’s also filled with bizarre details, hidden features, and unexpected references that most players completely miss. And thanks to OnlyAbidoang, we now have a full list of 50 fascinating facts that will have even the most veteran Simmers going, “Wait, what?!”

So let’s dive into the wildest secrets hiding in plain sight inside The Sims 4.

🍼 Sims, Fire, and… Immortality?

  • Babies, toddlers, infants, and pets are completely immune to fire. Yes, pets can get singed—but they’ll be fine.
  • If you scale up a baby in Build Mode using the bracket keys, you can literally make a Kaiju Baby. The chaos is unreal.

🧠 Werewolves & Emotions = Mushrooms?

  • A vegetarian werewolf won’t hunt for meat—they’ll bring back mushrooms. Peaceful, plant-based lycanthropy.

🧶 Raccoons, Whiteboards, and Sandwich Memes

  • If you’re in Business & Hobbies and wear a raccoon tattoo, Trashley Reelpearson (a raccoon in disguise) will compliment you and give a discount. Wear the full raccoon costume, though? They get offended.
  • The whiteboard in that pack features a sketch nod to Gordon Ramsay’s “idiot sandwich” skit. Iconic.

🐦 Birds, Poly Models, and Hilarious Mixups

  • Old bird models from packs like Vampires are comically low-poly compared to newer birds from Cottage Living.
  • You can see both styles flying in the same world—and it’s hilarious.

🐴 Horses Can’t Use Stairs, But They Can Hack Platforms

  • Horses are incapable of using stairs, but you can stack one-step platforms to create a makeshift “staircase” that kind of works.

🎇 Fireflies, Owl City, and Snowpal Romance?

  • The fireflies build item references Owl City’s “Fireflies” lyrics.
  • Sims can tell snowpals different types of stories based on their mood. There’s even a hidden flirty version—though only childish older Sims can trigger it.

🎮 Pop Culture Easter Eggs Galore

  • The arcade machine costs 1,337 simoleons—a “leet” reference from early internet culture.
  • The heart gem in Crystal Creations references Steven Universe: The Movie.
  • A chair in Growing Together nods to the Aldecaldos from Cyberpunk 2077.
  • A base game lamp named The Sovereign references the villain from Mass Effect.

🧑‍🍳 Cooking, Collecting, and Cringe

  • Dumpster diving in Eco Lifestyle can uncover throwback furniture from The Sims 1.
  • Some Growing Together furniture matches base game items—suggesting they were originally intended for the base game. Yep, monetization strikes again.

🦷 Losing Teeth Is Now a Milestone?

  • A Sim’s first lost tooth is tracked as a Milestone (aka an achievement).
  • EA hyped this as a “new memory system,” but it’s really just a badge with a cute notification.

🧛‍♂️ Occult Powers, but Make It Existential

  • Sims with the Skeptical trait are immune to all occult powers. If they become an occult Sim, they get tense using their own powers and question their identity. Dramatic.

💀 WooHooing the Grim Reaper

  • Yes, you can WooHoo with Grim. The game gives your Sim a special buff based on how “good” the reaping was.
  • Add Grim to your household, remove his hood in CAS, and—surprise! He now uses a default face preset.

🏙️ The Urbz are Back?!

  • Business & Hobbies brings back characters like Cannonball Coleman and Gramma Hattie from The Urbz: Sims in the City.
  • If you befriend Cannonball and co., they’ll reveal Ollie Mark’s mysterious heritage—tying back to The Urbz console lore.

🧪 Old Skills, Hidden Traits, and Scrapped Features

  • A Reaping skill existed in 2014, likely meant for an early Grim gameplay concept, but it was quietly removed. It later returned in spirit with the Life and Death expansion.
  • The Kindness Ambassador trait from 2018’s Positivity Challenge can still be unlocked with a cheat.

🌦️ Weather, Ghost Trains, and Sims Slipping on Marbles

  • In Ravenwood, you might see a ghost train cross the bridge. Blink and you’ll miss it.
  • Sims can slip on marbles from For Rent, and pets can even eat them. They’ll be fine.
  • Weather from Seasons doesn’t always apply in newer worlds like Ravenwood, despite owning the pack.

👽 Alien Fingerprints and X-Ray Disasters

  • Arrest a disguised alien in the Detective career and their fingerprint scan breaks the machine.
  • Perform surgery on one in the Doctor career to unlock a secret achievement.

🎨 Secret Art Tricks and Build Mode Shenanigans

  • The “Sun Beam Scribble” from Cats & Dogs becomes one large artwork if you arrange all four swatches.
  • The lava lamp blob from Strangerville jiggles slightly if you move it in Build Mode. Why? Who knows.

🎉 Sims That Run Like the Wind (Sort Of)

  • There’s a hidden fast run animation that’s way quicker than jogging—but it only appears in specific contexts (like when throwing up or rushing to help burglars).
  • OnlyAbidoang even made a mod to unlock this running animation for everyday use.

🏡 You Can Live in Vacation Worlds… Kinda

  • Using Paranormal Stuff, you can sneakily live in Selvadorada or Granite Falls by converting lots into haunted houses. But be warned: traveling is buggy, and it’s not officially supported.

🍧 Ice Cream Is Still Paywalled

  • Ice cream exists in Cool Kitchen Stuff and High School Years, but they’re completely different versions—both paywalled. And yes, this was worth mentioning again.

These are just some of the facts highlighted by OnlyAbidoang—and they perfectly capture just how weird, broken, detailed, and meme-worthy The Sims 4 truly is. Whether it’s Grim WooHoo buffs or Sims slipping on marbles, it’s clear that even after a decade, this game still has surprises up its sleeve.

Frequently Asked Questions

Can you really WooHoo with Grim in Sims 4?

Yes! Your Sim can WooHoo the Grim Reaper and will get a special moodlet based on how “well” the interaction went.

Why are babies objects in Sims 4?

Babies in The Sims 4 are coded as objects, which is why they can be resized or moved in Build Mode. This changed a bit with the addition of infants in Growing Together.

What’s the difference between jogging and running?

Jogging is the usual Sim movement. Running is a hidden, faster walkstyle that appears during specific events. You can unlock it with mods.

Can I live in a vacation world without mods?

Yes, if you convert a lot into a haunted house using Paranormal Stuff. However, traveling between worlds will be limited and buggy.

Is there really a poop joke in the game?

Absolutely. A treat in Cats & Dogs can make pets poop out a gold bar worth 6006 simoleons. Flip the number upside down—it spells “poop.” Classic EA.
