Value to the core loop
The official loop is steal eggs, hatch, feed to level, earn money, upgrade the lab. Rankings favor systems that make that cycle faster or safer.
Raise an Anomaly Tier List
This Raise an Anomaly tier list ranks systems, not unofficial pet nicknames. S-tier picks improve every steal-hatch-feed cycle. Exact formulas stay out until they are sourced.
Updated
Source-checked claims
Official description and group shout outrank community wikis. Community systems such as the treadmill are listed, but they are not treated as proven math.
Best current priorities
SUnlocks
Speed / treadmill
Community reports say Speed decides which zone you can steal from. If you cannot reach the egg, nothing else on this list matters.
SGrowth
Feeding / food
The official page tells you to feed baby anomalies to level them. Levels are how the art and the loop both say you earn more.
AEconomy
Lab upgrades
Cash from parked anomalies funds Speed, food, Plot, and later Merge. Upgrade the lab before buying comfort.
ARoster
Eggs and hatching
You cannot feed what you never stole. A clean hatch into an empty plot beats dying on a second steal.
BLate loop
Merge Machine
Announced 2026-09-16. Recipes are unpublished, so Merge is a B until a recipe table exists. Do not dump your only earner into it.
CPaid
Gamepasses
X2 MONEY and X2 GROWTH SPEED exist as products, but the 2026-09-16 API snapshot marks every pass as not for sale.
Re-rank after each update
The 16 September 2026 shout added a New Zone, Merge, and Fairy Cake. When Admin Abuse lands, check whether Speed or Merge moved before trusting this Raise an Anomaly tier list.
FAQ
Tier list FAQ
Why are named anomalies missing from the Raise an Anomaly tier list?
Hatch odds and cash-per-second tables are unpublished. Ranking Batty above Buddy from a community wiki would be a guess. The anomalies database keeps artwork-backed entries instead.
How often is the Raise an Anomaly tier list updated?
After group shouts, zone drops, and Merge changes. The date on this page is the last check.
