Slime RNG has a hidden crafting system that most players walk right past. Instead of purely relying on rolls, you can combine lower-rarity slimes into far more powerful creations, with stats that dwarf their ingredients. The catch: you need to physically track down 8 recipe scrolls hidden across the game's zones in Roblox, and none of them are exactly obvious.
How do you unlock crafting in Slime RNG?
Before any recipe scroll does anything useful, you need the crafting machine active. Head to the Heaven biome at level 7, move to the right side of the area, and interact with the machine there. Clicking the green Buy button costs 1M money, after which the crafting system opens up.
Once purchased, crafting machines appear in the Heaven area and then again every second or third zone after it, so you won't have to travel far to craft once you have your ingredients.
Use Slime RNG codes before pushing into Heaven to stack early money boosts. Reaching zone 7 without any buffs takes noticeably longer.
Also worth knowing: if you use rebirth, your zone progress resets and you'll need to physically re-unlock each area before revisiting recipe locations. The recipes themselves stay in your crafting menu after you've collected them, but you can't access zones you haven't re-unlocked post-rebirth.

All Slime RNG crafting recipe locations
Each recipe scroll is tied to a specific zone. The table below gives you the full picture before we get into the individual locations.
The Graveyard recipe's resulting slime name and stats are not yet confirmed. The ingredient drop rates are documented, but treat that crafted slime's details as subject to update.
Cave recipe (Zone 6)
Teleport to the Cave zone and walk toward the railway track that leads to the blocked cave on the right side. Before you reach the cave entrance, look for a large vine on the ground. The recipe scroll is tucked behind it. Hold E to collect it.
Crafty Slime stats at level 1: 228 HP, 76 Damage.
Ingredients: Lucky Slime (1 in 21.5K), Rocky Slime (1 in 13.9K), Mushy Slime (1 in 7.77K).
Jungle recipe (Zone 8)
In the Jungle area, walk straight until you spot a palm tree with three branches on your right. Behind it, on top of a rock, sits the recipe scroll.
Thorn Slime stats at level 1: 420 HP, 140 Damage.
Ingredients: Orbit Slime (1 in 126K), Icy Slime (1 in 86.1K), Stump Slime (1 in 35.9K).
Mushroom Forest recipe (Zone 10)
Find the smallest red mushroom in the zone. The scroll is attached to the stem of that mushroom. According to Destructoid's testing, you'll need to climb the mushroom to grab it.
Geode Slime stats at level 1: 813 HP, 271 Damage.
Ingredients: Ninja Slime (1 in 1.26M), Guest Slime (1 in 861K), Aegis Slime (1 in 215K).

Redwood Forest recipe (Zone 12)
From the Redwood Forest spawn, walk toward the far end of the zone. On the right side, there's a log lying on the ground. The scroll is underneath it, near the edge of the Meteor zone.
SlimeSlimeSlime stats at level 1: 2.02K HP, 676 Damage.
Ingredients: 3x SlimeSlime (each at 1 in 10.7M). This one is genuinely expensive to craft.
CandyLand recipe (Zone 14)
Right at the CandyLand entrance, look to your right. There's a chocolate bar with a red wrapper. The scroll is behind it. This is one of the easier ones to find once you know what you're looking for.
Puffy Slime stats at level 1: 4.2K HP, 1.4K Damage.
Ingredients: Unicorn Slime (1 in 17.9M), Petal Slime (1 in 39.1M), Derpy Slime (1 in 89.7M).
Getting to CandyLand and beyond requires significant money. Unlock the Teleport upgrade from the upgrades tree (costs 1M) to skip the manual zone-by-zone travel.
Crystal Cavern recipe (Zone 16)
Look for the stone arch in the center of Crystal Cavern. Climb to the top of it, and the scroll sits at the highest point. According to Destructoid, you can scale the walls to get up there.
Astro Slime stats at level 1: 12.3K HP, 4.1K Damage.
Ingredients: UFO Slime (1 in 478M), Blackhole Slime (1 in 1.07B), Bomber Slime (1 in 307M). Getting to Crystal Cavern itself is expensive, so make sure your money farming is solid before pushing this far.

Atlantis recipe (Zone 18)
Enter Atlantis and find the large temple structure. The scroll is behind this building. Destructoid places it behind a small stone mausoleum in the middle of the zone.
Sunny Slime stats at level 1: 24.3K HP, 8.1K Damage.
Ingredients: Pumpkin Slime (1 in 2.77B), Ouchy Slime (1 in 4.39B), Ember Slime (1 in 1.72B).
Graveyard recipe (Zone 21)
The final scroll is the most hidden. Walk through the Graveyard road and find the large grave beside a boulder near the eastern edge of the area. Jump inside the grave to collect it. The slime this recipe creates has a 1 in 237B chance and its name and stats are still being confirmed.
Ingredients: Monke Slime (1 in 15.3B), Waxie Slime (1 in 50.1B), Germy Slime (1 in 113B).
How do you actually craft a slime?
With a recipe collected and ingredients in hand, walk onto any crafting machine to open the crafting menu. Hit the Select button next to the recipe you want, choose your ingredient slimes, then press Craft. If you have duplicates, the autocraft option lets you burn through multiple batches without clicking each one manually.
The ingredient slimes are consumed permanently when you craft, so plan accordingly before committing.
Mutation tip from Destructoid: When you craft using slimes that share the same mutation (BIG, Shiny, HUGE, Inverted), you significantly increase the odds of the crafted result carrying that mutation. Mixing different mutations gives you a much lower chance. If you're targeting a specific variant, save up slimes with matching mutations before crafting.
What stats do crafted slimes have compared to rolled slimes?
Crafted slimes are meaningfully stronger than the individual slimes used to make them. The jump from ingredients to result is significant at every tier:
- Crafty Slime: 228 HP / 76 Damage (ingredients top out at 1 in 21.5K each)
- Thorn Slime: 420 HP / 140 Damage
- Geode Slime: 813 HP / 271 Damage
- SlimeSlimeSlime: 2,020 HP / 676 Damage
- Puffy Slime: 4,200 HP / 1,400 Damage
- Astro Slime: 12,300 HP / 4,100 Damage
- Sunny Slime: 24,300 HP / 8,100 Damage
