The Sims 4 Collectibles: Aliens
Aliens are rewarded to Sims who travel to space. Traveling to space requires you to purchase a Rocketship in buy mode, and have your Sims build it from scratch. Once you have a working rocketship, your Sims will need to explore space and complete text adventures. Collecting all aliens requires plenty of trips to space.
❗ Upgrading the Rocketship will help complete your Alien collection faster.
Image | Name | Rarity | Value | Description |
 | Live Space Squid | Rare | §165 | A gelatinous, docile organism that communicates via patterned pulses in its bioluminescent skin. |
 | Live Blue Slug | Rare | §165 | A parasite that inhabits the brains of larger organisms and effectively plays puppetmaster. Ostensibly extremophilic. |
 | Live Pink Whale | Uncommon | §165 | Vaguely reminiscent of our own cetacean mammals, this "space whale" manipulates the fabric of time and space in navigating its environment. |
 | Dead Space Squid | Uncommon | §150 | 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 Red Coral | Uncommon | §165 | Unlike its earthly counterparts, more than ninety percent of this coral-like structure is engaged in metabolic processes. |
 | Dead Red Coral | Common | §150 | Preliminary readings suggest that this "skeleton" emits a constant stream of short-wave transmissions -- often involving what appear to be numerical tallies. |
 | Dead Blue Slug | Common | §150 | Extracted from the body of its prior host, the specimen continues to move even after other life signs have long since faded. |
 | Dead Space Porcupine | Common | §150 | Anatomical analysis reveals that this specimen has both reptilian and mammalian reproductive features--perfectly fit for erratic meteorological patterns. |
 | Dead Pink Whale | Common | §150 | This organism's vital fluids contain traces of phosphorus, glowing for a short period of time when exposed to oxygen. The next "fossil" fuel? |
 | Live Space Porcupine | Common | §165 | This "porcupine" exhibits shy, skittish behavior, expelling its "quills" to tranquilize would-be predators and making a hasty retreat thereafter. |
 | Xenolife-Friend Wall-Mounted Reminder | Plaque | §0 | Awarded to household when completing the "Aliens" Collection. |
