Raise an Anomaly Anomalies: Known Roster, Attributes, and How Entries Are Obtained

Quick answer

Raise an Anomaly does not print an official anomaly count — the store page only asks “Can you unlock and discover all anomalies?” The known entries fall into two groups: four creatures visible in official art that are known only by community nicknames, and more than twenty names observed during gameplay. Every known entry is compared below with its displayed attributes and how it was obtained.

• Official-art entries (community nicknames, not store-page names): Yellow Smiler, Pale Screamer, Forest Grin, and Crib Guardian. Fan rosters list all four with rarity “Unknown” and no published odds; one roster calls the fourth entry “crib humanoid” instead — both labels are unofficial, and no store-page name exists.
• Gameplay-observed names: Batty, Dragon Snail, SCP-079, Silver Leftovers, Pet Rocks, Buddy, Wombo, Teddy Bear, Tickles, Young Rory, Smiler, Toothy, Butterfly Dragon, Chair, Two-Headed Deer, Beady Common, Pizza Guy, Giant Nose, One-Eyed Owl, Locust Anomaly, Frog, Horse, and Dragon.
• Attributes shown per entry: displayed cash per second (changes with level and feeding), rarity labels, and official growth-stage art for three of the four nicknamed families.

Gameplay-observed anomaly roster

The names below all appeared on screen during observed Raise an Anomaly play. Every cash figure is a single observation that changes with the anomaly’s level and feeding, so treat these as snapshots from one run rather than fixed stats.

The official game description does not publish a complete roster; it only promises that hatching “unlock[s] new anomalies.” Treat this roster as a snapshot of known entries and recheck it after game updates rather than assuming undocumented stats for any anomaly.

How anomalies are obtained

The official loop is: “Steal eggs from SCP monsters … Hatch eggs to unlock new anomalies … Feed baby anomalies to level them up! … Earn money and upgrade your lab! Can you unlock and discover all anomalies?” Third-party descriptions match it. In observed play, eggs are carried home from named parent monsters — one player goes to “steal one of Verity’s eggs,” places it in the plot, and hatches it. Verity herself is a parent monster, not a raisable roster anomaly.

There is no published egg-to-creature table: egg appearance does not provide a confirmed guarantee for one exact anomaly, so any egg-to-anomaly pairing in the roster above is a single observed hatch, not a rule. Two roster entries skip eggs entirely — the Locust Anomaly was bought from a “Limited” shop section, and Wombo was also purchased rather than hatched.

Displayed attributes: cash per second and rarity labels

Each hatched anomaly displays a cash-per-second value, and that number is the attribute to judge entries by: “Look at its displayed cash generation.” Observed values ranged from about $1.09/s for a fresh Batty and $230/s for a fed Tickles up to $3.1 million/s for Toothy and $198 million/s for a hatched Locust. These are single-run observations — Raise an Anomaly has not published hatch seconds, food drain, or cash per level, so there is no official stat sheet to compare against.

Anomalies also carry rarity labels. One player noted, “The blue one rare. I don't have any epics, but I almost have all the rares,” and eggs in one run displayed odds of 1% and 8%. Those odds were seen on eggs during play, not published per anomaly, and no official rarity colors exist. Fan rosters that avoid invented numbers follow the same rule: no invented 1-in-N, no invented $/s, no invented rarity colors — missing values render as “not yet observed.”

Growth-stage art for the nicknamed families

Official Raise an Anomaly thumbnails show what three of the four nicknamed families look like as they grow, using three different progress words — one three-panel shot labels Level 1, Level 50, and Level 99999.

Data table

Data table

Family (Community Nickname)	Progress Shown	Appearance In Official Art
Yellow Smiler	Level 1	“yellow grinning sphere. Cute, portable, easy to steal-adjacent in marketing”
Yellow Smiler	Level 50	“sphere with arms, claws, and legs. The joke turns”
Yellow Smiler	Level 99999	“elongated yellow adult with a stretched smile in indoor light”
Pale Screamer	Age 1	“emaciated infant, mouth open, bath props (duck, bottle)”
Pale Screamer	Age 100	“tall pale humanoid, long limbs, reaching camera”
Forest Grin	Day 01	“player holding a yellow smile ball — overlaps smiler imagery”
Forest Grin	Day 100	“giant crouched grin in the trees, player tiny in front”

These progress words are shown in art, not confirmed as HUD stats. It is not confirmed whether Level, Age, and Day are separate meters, whether baths add Age while steak adds Level, or whether 2x growth affects the post-hatch morph. Until an in-game screenshot shows all three at once, assume you will see one number that goes up when you feed after a hatch — and treat 99999 as marketing language for “there is a long tail.”

The in-game index

Raise an Anomaly tracks your collection with an in-game “index.” Players discover it mid-run — “Oh, wait. This is the index.” — and treat completing it as the roster goal: “I think we need to steal to have them all completed to complete a list.” The index also grants rewards: “Also, from the index, we can get a few stuff.” The index is the in-game counterpart to any published roster, but its complete entry list is not documented yet, so open it in-game to see the current entries.

How to compare roster entries

Judge each entry after it hatches rather than by its egg or appearance. Check what the anomaly produces per second right now, compare it with the creatures already using your space, and place it if it improves your base — then feed it only when that investment fits your current economy. Do not use name or size as a shortcut: small and unusual residents can display strong output, while a large creature can still underperform your current lineup. Because feeding can change a resident’s level and observed output, re-read the displayed number before comparing entries — an old comparison may no longer be accurate.
