New mutation tiers
likelyThe listing names mutations as the subject of the update, so something in that system changes. What changes in numbers has not been published, which leaves the count and the multipliers open.
The next content drop, separated into what is confirmed and what is only a pattern.
Time until the earliest reported start
19 September 2026
Targets 14:00 UTC on 19 September. A second source reports 22:00 without naming a timezone, and the developer has published no time at all, so treat the exact hour as provisional.

This page used to report two conflicting third-party start times and label the hour unknown. The official listing has since settled it: 14:00 UTC on 19 September 2026, with the window open until 26 September 2026. The earlier third-party reports are kept in the table below because they were part of the record, not because they are still live.
| Reported start | Source kind | Grade |
|---|---|---|
| 14:00 UTC (official) | Roblox Virtual Events API, event 1891101641449538134 | S1 |
| 22:00, timezone unstated | a competing fansite | S4 |
Neither figure is official. The only thing a reader should take from this table is that the day is solid and the hour is not, which is more useful than a single confident time that turns out to be wrong.
The developer has published one sentence about the mechanics and nothing else: mutations can be stacked with weather traits. No mutation list, no multipliers, no prices and no patch notes. The expected list below is pattern reading, and it is now framed against a confirmed theme rather than against nothing.

The in-game Index already shows locked silhouettes, and new hatchables are the cheapest way for a pet game to give a mutations update something to apply to.
Three of the four game passes were withdrawn from sale four days before this window opens, which is what a shop restructure looks like from the outside.
A major update is the conventional moment for a pet game to release its first code, since that is when lapsed players are most likely to look.
Preparation here is cheap and does not depend on knowing what is coming. Everything below is worth doing before any content update in this genre, which is exactly why it can be written before the patch notes exist.
The databases are rebuilt against the new version rather than patched around it. Egg spawn counts and the shop odds are the first two things rechecked, because a content update does the most damage to those. This page keeps its confirmed list and gains a results section, so the gap between what was predicted and what actually shipped stays visible, with the original prediction left in place and the outcome marked against it.
If the update introduces a redeem code, it appears on the codes page only after we have redeemed it. If it introduces new pets, they appear in the roster with their own grade rather than being folded into the existing table as though they had always been there.
Update 1 is the rare case where the third-party record is fuller than the official one, because the developer shipped it without patch notes. Use these as a record of what landed, not as a source of figures: the spoken captions are graded S4 and specific numbers should come from this site's tables.
