Slick Rick Black Market: Location, Unlocking, Items and Prices
Slick Rick randomly appears in the Alien Biome. He won't stay on the map permanently, so players need to find him before he disappears.
According to player reports, the Black Market now uses a global spawn system. When Slick Rick appears in one server, he also appears in all other servers. Players can also join the official Steal a Egg Discord server and enable Black Market notifications to avoid missing his appearances.
How to Unlock the Black Market
The first time you encounter Slick Rick, you must complete a series of minigame challenges to unlock access to his Black Market items.
The challenge begins with a search for black crates. You'll need to pick their locks while avoiding guards and traps. Once you find the correct crate, a 10-second escape countdown begins, so you must get out in time.
The challenge then moves to a cannon and vehicle battle. Take control of the cannon and vehicle, and defeat 20 competing vehicles to complete the escape.
After successfully completing the challenge, you'll receive a Rainbow Executive Raccoon (Legendary) as your reward and unlock access to the Black Market.
What Does the Black Market Sell?
Slick Rick sells Mutation Shards, special eggs, weapons, and base skins. Below is a list of the currently discovered items and their displayed prices.
Mutation Shards
| Item | Quantity | Price |
|---|---|---|
| Fractured Mutation | ×5 | 0.6H of Income |
| Nitro Mutation | ×5 | 0.6H of Income |
| Blacklisted Mutation | ×2 | 1.5H of Income |
| Spirit Bloom Mutation | — | 8.8H of Income |
Eggs
| Item | Quantity | Price |
|---|---|---|
| Smuggled Egg | ×1–3 | 1H of Income |
| Contraband Egg | ×1–2 | 2H of Income |
Weapons
| Item | Price |
|---|---|
| Mushroom Sword | 2.3H of Income |
| Dual Blades | 4.1H of Income |
| Coral Trident | 7.3H of Income |
| Blossom Katana | 13H of Income |
| Enlightened Scythe | 23.2H of Income |
Base Skins
The currently discovered base skins include Jungle, Coral, Lunar, Sakura, and Mushroom. Mushroom has a displayed price of 5.4H of Income, while the exact prices of the other skins have not yet been confirmed. We'll update this section as soon as more pricing information becomes available.
Keep in mind that H of Income is based on your own hourly income in the game. This means Black Market prices can vary between players rather than being fixed Cash amounts.
How Much Does It Cost to Refresh the Black Market?
If the current stock doesn't include the item you want, you can spend Robux to refresh the Black Market inventory.
BLACK MARKET REFRESH COST
49 Robux
Each inventory refresh costs 49 Robux.
The available items may change after refreshing, but there's no guarantee that you'll get a specific Mutation Shard, egg, or weapon. It's a good idea to check the current stock before spending Robux on another refresh.
Black Market Mutation Success Rates and Multipliers
The success rates and income multipliers of several Black Market mutations are also worth checking. According to the community Mutation Guide:
| Mutation | Success Rate | Income Multiplier |
|---|---|---|
| Spirit Bloom | 100% | ×2.5 |
| Blacklisted | 25% | ×2.5 |
| Fractured | 10% | ×2.75 |
| Nitro | 16% | ×2.75 |
The success rate refers to the chance of successfully applying a mutation using its shard, while the multiplier represents the income bonus after the mutation is applied. These are two different things and shouldn't be confused. The figures above come from a community mutation guide, not an official developer announcement.
Stormlands Biome and the Skyfall Event
Stormlands is a new biome introduced in Update 13, located between Prehistoric and Cosmic. Players need at least 150M Speed to enter, according to community testing.
The area features new pets and a recurring event called Skyfall. Players can collect Thunderstones during the event to exchange for the limited-time Stormy Egg, while also searching for the special materials needed to unlock Thunderous Mutation.
Skyfall Event Schedule
Frequency
30 min
Duration
5 min
Starts every hour at :00 and :30.
When the event begins, rocks fall from the sky. Players need to break these rocks to collect Thunderstones. Regular rocks provide event currency, while special rocks infused with lightning have a chance to drop another rare material called Storm Glass.
These two materials serve different purposes: Thunderstones are used to purchase Stormy Eggs, while Storm Glass is required to activate the special machine inside the hidden cave.
How to Get the Stormy Egg: Price and Pet Income
Stormy Egg is a limited-time egg introduced in this update and available in Stormlands. Players need to participate in the Skyfall event, collect enough Thunderstones, and exchange 200 Thunderstones for one Stormy Egg.
STORMY EGG PRICE
200 Thunderstones
The confirmed egg pool currently includes six pets:
| Pet | Rarity | Income |
|---|---|---|
 Stormstring |
Legendary | $22.5K/s |
 Nimbus |
Legendary | $35K/s |
 Sparkfield |
Mythic | $160K/s |
 Cloudcurler |
Cosmic | $6M/s |
 Stormflutter |
Secret | $700M/s |
 Stormlord Titan |
Eternal | $5B/s |
Stormlord Titan has the highest income in the egg pool, generating $5B per second. Stormflutter is the highest-earning Secret pet, with an income of $700M per second.
If your goal is to collect the new pets, make the most of each Skyfall event to gather Thunderstones. However, reliable hatch rates for the six pets have not yet been confirmed, so it's best not to assume their individual drop chances based on rarity alone.
How to Get Thunderous Mutation
Besides the Stormy Egg, Stormlands also features a hidden activity that allows players to obtain the brand-new Thunderous Mutation. The process involves collecting Storm Glass, activating a hidden machine, and completing the Storm Rush event.
First, look for lightning-struck special rocks during Skyfall. Breaking these rocks has a chance to reward you with Storm Glass. Once you have collected three pieces of Storm Glass, head to the hidden cave in Stormlands, find the Storm Conductor, and insert the materials to activate the machine.
Once activated, the machine triggers Storm Rush. Players need to fly around inside the cave and collect Sparks. The game indicates that you can hold Space to fly upward and Shift to fly downward.
Once you have collected 150 Sparks, find the NPC Rumble and open the Thunder Trade-In interface to exchange them for one Thunderous Mutation.
How to Get Thunderous Mutation
Thunderous Mutation has an income multiplier of ×2.75. Its appearance features dark storm clouds and lightning effects, making it one of the new mutations introduced in this update.
Keep in mind that the official announcement states that players participating in the server will receive the new mutation after the machine is activated. However, the in-game Thunder Trade-In interface also shows an option to exchange 150 Sparks for one mutation. Players can follow the rewards and exchange options actually available in their game.
