Pets Universe tier list
A tier list is a claim about relative value, and relative value needs two numbers: how rare a pet is, and what people will trade for it. For 3 of the 4 pets we track, neither number is published. So this page ranks what can be ranked, states the method it will use for the rest, and does not pretend a guess is a ranking.

Exclusive · developer-published odds
“S” here means top of the published ladder, nothing more. With one confirmed rarity there is no distribution to rank against — a single point is not a curve.
Unranked — known by name only
The method that will rank them
Hatch odds set the floor
A pet at 1 in 1,000,000 cannot be common. Published odds are the only objective input a tier list gets, and they come first.
Demand moves it
Rarity is necessary, not sufficient. A rare pet nobody wants trades below a common pet everyone does — so trades, not odds, decide the top of the list.
Utility breaks ties
Where two pets share a rarity and similar demand, the one that does something useful in play wins the tie.
No data, no rank
Pets without a published rarity stay unranked. A tier list padded with guesses is worse than a short honest one.
What unlocks a real tier list
- The in-game pet index, read out — it lists names and rarities, which turns the unranked block above into real rows.
- Two independent traders agreeing on brackets — that is the threshold this site publishes values at.
- Any developer post that prints odds for a pet that is not already here.
In the meantime, the four-step method on the values page lets you price a specific trade without waiting for this list.
