Quick answer
Ride A Pet weather events can add Shocked, Volted, Rage, Void, or Eternal mutations to eligible pets and eggs. Reported speed and income multipliers run from 2× to 100×. Weather mutations do not stack with one another, but the in-game index says they can stack with hatch mutations.
How to get mutations
Weather events give pets mutations that improve speed and cash income. Place the pet in your ranch pen or ride it during the event. Pets left in your inventory cannot catch a weather mutation, according to Pro Game Guides’ September 16 walkthrough.
Watch the weather indicator while collecting eggs. The guide reports five-minute events and a chance for eligible pets to mutate; being outside does not guarantee an application. It also reports that eggs on the map become mutated during the event, and eggs already placed in a pen can receive the weather effect before hatching.
Weather types and mutation multipliers
| Weather | Mutation | Reported speed and income multiplier |
|---|---|---|
| Thunder | Shocked | 2× |
| Volt | Volted | 3× |
| Rage | Rage | 4× |
| Void | Void | 10× |
| Eternal | Eternal | 100× |
The game’s Index → Mutations → Weather Mutations panel names all five effects. The multipliers above follow the Pro Game Guides effect summary; its published panel screenshot also shows the matching mutation names and money multipliers.
Eternal has the highest listed multiplier. However, compare the actual pet as well as its mutation: base speed and base income still determine whether it beats another mount or ranch earner. The pets guide compares those different jobs.
Which pets and eggs can mutate?
- Pets placed in the pen: leave the pets you want to improve on your ranch during weather.
- The pet you are riding: the walkthrough reports that a ridden pet can receive the weather mutation too.
- Pets stored in the inventory: move them out if you want them eligible for weather effects.
- Eggs waiting in the pen: they can receive a mutation before hatching. A mutated egg has a chance to hatch a pet with that effect; it is not a guaranteed result.
If a useful weather event is active, finish your egg return and place the egg in a nest rather than leaving it in the backpack. The egg guide covers the return routes and rare-egg search zones.
Can mutations stack?
Weather effects and hatch effects are different categories. The published in-game Weather Mutations panel explicitly says “Stacks with hatch mutations.” A blanket statement that no mutations can stack misses this distinction.
For two weather effects, the Pro Game Guides walkthrough describes replacement rather than stacking: a higher-value weather mutation replaces the lower one. Its example is Shocked being replaced by Volted. Do not calculate a combined 2× × 3× weather bonus from those two labels.
Why did your pet not mutate?
Weather mutations are a chance, not a guarantee. Work through the causes in order:
The pet was in your inventory
Only pets on the ranch or the pet you are riding are eligible, according to the walkthrough. A stored pet cannot catch a weather effect.
The event ended before the roll landed
Each event runs about five minutes. A pet placed with seconds left has far fewer chances than one already on the ranch when the weather started.
It rolled and simply missed
No per-pet probability has been published. Repeat attempts across several events rather than assuming the placement was wrong.
The mutation was replaced, not lost
If a pet had a lower-value effect and a stronger weather event hit, the earlier label is gone by design. Check the card for the newer name before concluding the pet lost its bonus.
The egg hatched without the effect
A mutated egg only has a chance to hatch a pet with that mutation. An ordinary hatch from a mutated egg is an expected outcome, not a bug.
If none of these explain your result, the current version may have changed the rule. Compare a pet’s card before and after one full event before trusting any multiplier chart, including the one on this page.
Making use of a mutated pet
Use an improved riding pet on longer egg runs, where movement speed helps you get back before the egg breaks. Place strong income pets in ranch slots so their money bonus contributes toward upgrades and rebirth requirements. A fast mount and a good ranch earner need not be the same pet.
Before selling a duplicate, compare its mutation and current card values with the pet you plan to keep. Also keep the named pet needed for your next rebirth rather than selling it just because another mount is faster.
