The Alien Collection is one of the many collections that can be obtained and collected in The Sims 4. The collection includes dead Aliens and Aliens that are alive. You need 10 different Aliens to complete the collection.
If you put your dead Aliens on display in your home they can be enabled to provide a +3 Confident emotional aura in a room. The ones that are alive give +3 Environment. Collections can be obtained by the whole household.
How to collect all Aliens
The only way to collect dead or alive aliens is to build a rocket ship and explore outer space. When your Sims is out there there is a chance they collect Aliens or Space Rocks. If you want to collect all of them you need to make a lot of trips into space.
Tip: If you upgrade your rocket ship, you can collect the aliens a bit faster as usual.
Tip: If you have an Alien Sim in your household (requires The Sims 4 Get To Work) you’ll be able to resurrect Dead Aliens. This will help you to complete the collection faster.
You can find 10 different Aliens in space.
Dead Pink Whale
This organism’s vital fluids contain traces of phosphorus, glowing for a short period of time when exposed to oxygen. The next “fossil” fuel?
Dead Blue Slug
Extracted from the body of its prior host, the specimen continues to move even after other life signs have long since faded.
Dead Red Coral
Preliminary readings suggest that this “skeleton” emits a constant stream of short-wave transmissions–often involving what appear to be numerical tallies.
Dead Space Porcupine
Anatomical analysis reveals that this specimen has both reptilian and mammalian reproductive features–perfectly fit for erratic meteorological patterns.
Dead Space Squid
With six appendages, partial transparency, and an unusually reflective outer membrane, this specimen likely evolved on a water-planet before arriving at the point of discovery.
Live Space Porcupine
This “porcupine” exhibits shy, skittish behavior, expelling its “quills” to tranquilize would-be predators and making a hasty retreat thereafter.
Live Pink Whale
Vaguely reminiscent of our own cetacean mammals, this “space whale” manipulates the fabric of time and space in navigating its environment.
Live Red Coral
Unlike its earthly counterparts, more than ninety percent of this coral-like structure is engaged in metabolic processes.
Live Blue Slug
A parasite that inhabits the brains of larger organisms and effectively plays puppetmaster. Ostensibly extremophilic.
Live Space Squid
A gelatinous, docile organism that communicates via patterned pulses in its bioluminescent skin.

Xenolife-Friend Wall-Mounted Reminder
The Xenolife-Friend Wall-Mounted Reminder is a proud gift from the Simsonian Xenolife Appreciation Society, where it states in fine print to rotate the terrariums a few times a week, just so your extraterrestrial friends and cadavers get their recommended healthy dose of gamma-ray bursts.
You can also unlock all the Aliens with the Buy Debug mode cheat (adds extra objects) found on the Cheat Code Master List. Make sure you put the Aliens in your inventory to complete the collection.
