The UFO event in Slim RNG has finally arrived. There is a lot to cover, from a brand-new free-to-play feature that players have been asking for to a limited-time event that can reward you with jackpot spinks worth 300 Robux. Here's everything you need to know about the Slime RNG UFO event.
Slime RNG UFO Event Update Guide
How Slime RNG UFO Event Works
The UFO event is the headline feature of this update. The UFO spawns every hour during the update window, and you can keep track of the timer in the top-right corner of your screen. It'll show you both the countdown and the current location.

About 20 minutes before the event starts, an official countdown appears so you know when to get ready. Plus, you can also see the location with a rainbow lining whenever you want to teleport. That's where the UFO currently is.
The UFO drops loot as it goes. You can follow it around, or if you have the Auto Collect game pass, you can stay anywhere on the map and still pick up the drops without chasing it.

The UFO drops a mix of:
- Food
- Boost Items
- Dice
- Jackpot Spins (worth 300 Robux in the shop)
- Power Fruits
The drops are RNG-based, so your results will vary. But the potential to walk away with a jackpot spin or a universe fruit just from playing makes this event easily worth participating in every single hour.
The Fruit Extractor
One of the biggest additions in this update is the Fruit Extractor, and if you are a free-to-play player, you will want to know about this one right away.

Before this update, the only way to remove a power fruit from your slime was to spend 40 Robux on something called the Fruit Recovery item. Now, the devs have added free-to-play machines scattered across the map, including in Zone 12, the Redwood Forest, that let you pull a power fruit off your slime without spending a single Robux.
However, the free method only returns 50% of your fruit back to you, while the Robux method gives you the full 100%. So you do lose half. But getting something back for free beats losing it.
New Slimes
This update introduced 8 new slimes to unlock. Here they all are:
- Frenchie
- Eggy
- Dumpy
- Chef
- Twinkie
- Bot
- Sushi
- Nighty
New Zones
Two new areas have been added to the map.
Ancient Portal

The Ancient Portal is a new zone with a cool visual style to it. Inside, you'll find a Crafting Machine, though there are no new craftable recipes added yet. The devs will likely add those in a future update.
Race Car Zone

This is the one you'll actually want to spend time in. The Race Car Zone is now the best zone in the game for farming both coins and goop. If you're grinding for resources, this is where you should be. The zone itself looks great, too.
New Upgrades to Unlock
Three new upgrade categories have been added:

Luck Upgrades
The luck stat has several new tiers added in this update: Galactic Look and Universal Look. Pushing the cap from 1,150 all the way up to 1,300, with more expected in future updates.
Goop Upgrade
A new goop upgrade has been added, too. You can get a 7.5% double goop chance, meaning enemies have that chance to drop twice the goop when you kill them. It's a great upgrade long-term, but it'll take a while to reach the high price.
Walk Speed
New walk speed tiers have been added, too. While this might seem minor, it helps you get around the map faster, including keeping up with the UFO during the event.
