How to Get Blacklisted Mutation in Steal an Egg (Update 13)

The only known way to get the Blacklisted Mutation is to buy it from Slick Rick, the new Black Market Dealer added in Update 13. It is sold for in-game Cash, and the price scales with your income. Slick Rick spawns at random in the Alien Biome (250B Speed), so you need to be in the right place when his notification fires. The event window closes on November 16 at 17:00 UTC (12:00 PM ET / 9:00 AM PT).

Below is the full route to the mutation, what it costs, how to apply it, and the honest answer to the question everyone is asking: how strong is it?

Is Slick Rick the Only Way to Get the Blacklisted Mutation?

As far as anyone has confirmed, yes. The mutation is described as exclusive to the dealer, and no egg, boss, fishing reward or fuse recipe has been linked to it. That makes it different from most mutations in the game, which come from hatches, events or machines.

Compare that with the other mutations Slick Rick sells. Fractured and Nitro came from earlier events and consumable shops, and Spirit Bloom came from the Sakura Incubator. Blacklisted is the new one, and it is the reason this dealer is worth the trip.

I would treat “only from Slick Rick” as the working answer, but it is still early. If the developers add a second route, or Slick Rick stays after the event window, this could change.

How to Buy the Blacklisted Mutation, Step by Step

1. Reach 250B Speed. The Alien Biome is where he spawns, and you cannot enter below that number.
2. Go to the far end of the map near the Alien Ferryman and wait with the game window open. Our Slick Rick location guide covers the exact route and what to do if he is not in the first spot you check.
3. Watch for the server-wide notification at the top of your screen. He has a small chance to spawn about every 30 minutes and is reported to stay around 5 minutes.
4. Find the black truck with gold rims and open the shop prompt.
5. Check the stock. Offers rotate, so Blacklisted may not be in the first lineup you see. One report says the shop shows only about three items at a time.
6. Compare the price to your income before you pay (next section), then buy.
7. Apply it to an unhatched egg straight away, so you are not carrying it around.

If your stock does not include Blacklisted, a reroll is reported at 49 Robux. That number comes from a single report, so confirm it on the prompt before you spend anything.

How Much Does the Blacklisted Mutation Cost?

There is no flat Cash price. The shop prices each offer in hours of your own income, so the same mutation costs more for a player with a stronger base.

Mutation	Listed price (hours of your income)	Listed stock
Fractured	0.6	x5
Nitro	0.6	x5
Blacklisted	1.5	x2

To work out your own number, take your income per second, multiply by 3,600 for one hour, then multiply by 1.5. A player earning $10B per second makes $36 trillion per hour, so 1.5 hours would be about $54 trillion.

Notice that Blacklisted costs roughly two and a half times as much as Fractured and has less than half the stock. That is a pricing hint that the developers consider it stronger, but it is not confirmation. I would not buy on the assumption of a specific multiplier.

You can find the full reported shop list, including bat skins and base skins, in our Slick Rick items and prices.

What Does the Blacklisted Mutation Do?

It is a pet income mutation, and the multiplier is unknown. Neither the developers nor the community wiki have recorded it yet. If you see a guide claiming “Blacklisted is x5” or any exact figure, it is a guess until someone shows the in-game card.

Here is how the known mutations compare, which gives you a benchmark to judge the Blacklisted result against once it is revealed:

Mutation	Reported multiplier	Route
Rainbow	about x3.5	Hatches, Admin Abuse
Fractured	about x2.75	Mutation Consumable, Rift shop
Thunderous	about x2.75	Stormlands, 150 Sparks
Spirit Bloom	x2.5 to x3 depending on the list	Sakura Incubator, now dealer stock
Dark Matter	about x2.5	Void Pearls, 30% chance

The community mutation multipliers list on the Steal an Egg is the place to check once Blacklisted gets an entry.

How Do You Apply the Blacklisted Mutation to an Egg?

Mutation items in Steal an Egg are applied to an unhatched egg, not to a finished pet. The usual flow for consumables is:

1. Place the unhatched egg in your pen.
2. Hold the mutation item.
3. Walk up to the egg and use the Apply Mutation prompt.
4. Read the message that appears. It tells you whether the mutation landed.

Some mutation items have a success chance below 100%, so you may need more than one attempt. One screenshot of a dealer Spirit Bloom shows a 100% success chance, which suggests dealer stock could be guaranteed. We have a single screenshot for that, and nothing for Blacklisted, so read the prompt on your own item before you assume. The Dark Matter mutation shows the same placement step in detail.

Which Egg Should You Put It On?

Since the mutation is only worth it if the pet earns enough, use this rule: put it on the egg that will become your biggest earner.

Here is why. The price follows your whole base income, but the gain follows only the pet you mutate. The table shows how fast the 1.5-hour price pays itself back at different multipliers. These multipliers are hypothetical, not confirmed.

Hypothetical Blacklisted multiplier	Pet earns half your income	Pet earns a tenth of your income
x2	about 3 hours	about 15 hours
x3	about 1.5 hours	about 7.5 hours
x5	about 45 minutes	about 3.75 hours

The pattern is clear. On your top pet, even a modest multiplier pays itself back quickly. On a mid-tier pet, it can take most of a day, and the event window may not leave you enough time to get that value back.

If you can only afford one copy, buy it for your single best egg. A strong mutation on a weak pet is a poor use of 1.5 hours of income.

What If Slick Rick Never Spawns for You?

Because he is random and short-lived, plenty of players will miss him. A few steps raise your odds:

• Stay in the Alien Biome for the whole window, rather than checking in now and then.
• Keep sound on so you hear the notification.
• Save your Cash instead of spending it before he arrives.

If he does not show, you are not stuck without a mutation. Two free routes exist: the Thunderous Mutation from Stormlands (150M Speed, 150 Sparks), and the Dark Matter mutation from Void Pearls. For the full patch timeline, see the Steal an Egg updates page.

Blacklisted Mutation Scams and Fake Guides

• There are no codes. Steal an Egg has no code system, so any “Blacklisted redeem code” is fake.
• The mutation exists only in Slick Rick’s van. Anyone selling it off-platform, asking for gift cards, or promising to “sell you Slick Rick’s stock” is running a scam.
• Beware exact multipliers. If a page lists a precise number with no screenshot, treat it as a placeholder.

Will the Blacklisted Mutation Come Back After November 16?

Unknown. The official event listing ends on November 16 at 17:00 UTC, and the developers have not said whether Slick Rick keeps visiting afterward. Past event mutations like Nitro became rare once their events ended, so I would not count on a second chance. If you can afford it during this window, buy it. If the dealer stays, you have lost nothing. You can confirm the official dates on the Roblox event listing.
