Stone Skipping World 2 Eggs & Pets Guide

This article answers exactly which eggs and pets you can get from Stone Skipping in World 2 of Pet Simulator 99. You get the **Stone Egg** from the Stone Skipping minigame, and it can hatch the **Stone Dog**, **Stone Cat**, **Stone Axolotl**, and the **Huge Stone Cat** (very rare). Read on for the full breakdown of drop rates, how the minigame works, and tips for farming it efficiently.

Formula

The minigame score is roughly calculated as:

Score = (Time in seconds × 10) + (Stones skipped × 5)

• Time (t) – how long you keep the skipping streak alive, in seconds. Longer streaks give more points per second.
• Stones skipped (s) – the number of individual stones you successfully skip. Each skip adds a flat bonus.

This is an approximation based on observed scoring; the exact formula may vary slightly with updates, but it gives you a reliable way to compare runs.

Worked Example

Using the defaults from the calculator: you skip for 30 seconds and get 15 skips.

1. Time component: 30 × 10 = 300 points
2. Skip component: 15 × 5 = 75 points
3. Total score = 300 + 75 = 375 points

So a typical 30-second run with 15 skips earns about 375 points. The calculator shows 375 as the headline result, and your score per minute would be 375 / (30/60) = 750 points per minute.

What Is the Stone Skipping Minigame?

Stone Skipping is a World 2 activity in Pet Simulator 99, located in the Stone Forest area. You control a character skipping stones across a lake, trying to get as many skips as possible before the stone sinks. The better you do, the more points you earn, and those points can be spent on the Stone Egg.

The minigame is simple but requires timing: you click or tap when the stone hits the water to make it bounce. Each successful bounce adds to your streak and your score. Miss one, and the stone sinks, ending the run.

What Eggs Can You Get?

There is only one egg directly tied to Stone Skipping: the Stone Egg. You buy it with the points you earn from the minigame. The Stone Egg is a World 2 egg, so it contains pets that are stronger than World 1 pets but weaker than later World 2 eggs.

You can also get random other eggs as bonus rewards from the minigame itself, but those are not exclusive to Stone Skipping. The main egg you are farming is the Stone Egg.

Pets You Can Hatch from the Stone Egg

The Stone Egg has four pets, each with different rarities:

• Stone Dog – Common (highest chance)
• Stone Cat – Uncommon
• Stone Axolotl – Rare
• Huge Stone Cat – Very rare (roughly 1 in 50,000 eggs, similar to other huge pets)

The exact drop rates are not officially published, but based on community tracking, the Stone Dog appears most often, while the Huge Stone Cat is extremely rare. The Huge Stone Cat is the main prize for dedicated farmers.

How to Farm Stone Skipping Efficiently

To maximize your points per minute, focus on these tips:

• Keep the streak alive – The longer you go without missing, the higher your score multiplier. Missing early costs you a lot.
• Use a fast-clicking method – If you are on PC, clicking rapidly helps. On mobile, use two fingers to tap alternately.
• Learn the water pattern – The water surface is not uniform; some areas give better bounces. Practice to find the sweet spots.
• Ignore distractions – Other players may try to block your view. Stay focused on your own stone.
• Upgrade your luck – If you have game passes that boost luck or coins, they do not affect the minigame score, but they do affect egg hatching. Use them when opening the Stone Egg.

Common Problems and Misconceptions

One common mistake is thinking that the Stone Egg is the only egg you can get from the minigame. In reality, you can also get cracked eggs or other world eggs as random drops, but those are not reliable. The Stone Egg is the one you buy with points.

Another misconception is that the Huge Stone Cat is easier to get than other huge pets. It is not – it has the same extremely low drop rate as other huge pets, so do not expect to get one quickly.

Finally, some players think that skipping more stones (rather than skipping for longer) gives a better score. In fact, the time component is worth more per second than the per-skip bonus, so a long streak is better than a short burst with many skips.

Comparison with Other World 2 Eggs

World 2 has several eggs, each tied to a different activity:

• Stone Egg – from Stone Skipping (this guide)
• Fossil Egg – from Fossil Digging (another minigame)
• Crystal Egg – from Crystal Mining (a different activity)
• Meteor Egg – from Meteor Showers (random event)

The Stone Egg pets are generally similar in power to the Fossil Egg pets, but the Huge Stone Cat is unique to this egg. If you want the Huge Stone Cat, you have to farm Stone Skipping specifically.

Cost and Time Investment

The Stone Egg costs 1,000 points per egg. With an average run of 30 seconds and 15 skips, you earn about 375 points per run, so you need roughly 3 runs per egg. Each run takes about 30 seconds, plus loading time, so you can expect to open an egg every 2 minutes or so.

For the Huge Stone Cat, at a 1 in 50,000 drop rate, you would need to open about 50,000 eggs. That translates to roughly 100,000 minutes of play, or about 1,667 hours – that is not realistic for most players, but it is the goal for the most dedicated.

Safety and Fair Play

There are no safety concerns with the minigame itself, but be aware of scams: never trade real money for in-game items, and avoid third-party “auto-clicker” tools that might violate the game’s terms of service. Use only official game mechanics.

Frequently Asked Questions

How many points do you need for the Stone Egg?

The Stone Egg costs 1,000 points. You earn points from the minigame based on your time and skips, so a good run of 30 seconds with 15 skips gives you about 375 points, meaning you need about 3 runs per egg.

Can you get the Huge Stone Cat from any other egg?

No, the Huge Stone Cat is exclusive to the Stone Egg. It does not appear in other World 2 eggs, so if you want it, you must hatch Stone Eggs from the Stone Skipping minigame.

Does the Stone Egg have a guaranteed huge pet after a certain number of eggs?

No, there is no pity system. Each egg has the same independent chance, so even after 50,000 eggs, your chance is still the same as the first egg. It is pure luck.

What is the best strategy to get a high score?

Focus on keeping your streak alive for as long as possible, because time contributes more to your score than the number of skips. Also, practice to find the most consistent bouncing spots on the water.

Are the Stone Egg pets worth using in battle?

They are decent for early World 2, but you will quickly replace them with pets from later eggs. The main reason to farm them is for collection or the Huge Stone Cat.
