How to Craft Slimes in Slime RNG — Recipes & Locations Guide

Slime RNG is a collection and combat game on the Roblox platform in which players continuously roll to acquire Slimes of varying rarities, while simultaneously exploring different zones and defeating enemies to earn coins. The Mega Update released on May 1, 2026, introduced the Crafting Machine to the game, allowing players to fuse Slimes together to create high-rarity Slimes that cannot be obtained through standard rolling. This guide provides a comprehensive overview of all craftable Slimes, including their detailed recipes, acquisition locations, and specific crafting procedures.

Unlock the Crafting

Before you can begin crafting, you must first unlock the Crafting Machine. Players need to unlock the following zones in sequence—Grasslands, Desert, Polar, Volcano, Islands, and Cave—until they finally reach Heaven. This entire process costs approximately 14,455,400 coins. The Crafting Machine can be found in the Heaven zone; simply click the purchase button and spend 1,000,000 coins to unlock the machine.

Once the Crafting Machine is unlocked, eight distinct crafting recipes will appear across the following zones: Cave, Jungle, Mushroom Forest, Redwood Forest, Candyland, Crystal Cavern, Atlantis, and Graveyard. Each recipe scroll appears as a brown parchment roll emitting a faint white glow; approaching one will trigger a "New recipe unlocked!" notification. Any recipes you collect will be permanently saved within the Crafting Machine's menu.

Tip: It is highly recommended that you purchase the Teleporter first. You can find the Teleporter under the "Player" branch within the "Upgrades" menu; it costs 1,000,000 coins to purchase. Once acquired, you can instantly teleport between any of your unlocked zones, significantly boosting your efficiency.

Crafting Recipes and Locations

1. Cave (Zone 6) — Crafty Slime

Recipe Location: In the center of the Cave Zone, follow the railway tracks to the right until you find a large patch of green vines. The recipe scroll is hidden behind these vines, situated near the stone archway that marks the cave's entrance.

Crafting Materials:

• Lucky Slime *1
• Rocky Slime *1
• Mushy Slime *1

Crafting Result: Crafty Slime (Rarity: 1/57.4K). At Level 1, its stats are 228 HP / 76 Damage.

2. Jungle (Zone 8) — Thorn Slime

Recipe Location: Upon entering the Jungle Zone, head straight all the way to the end. On the right-hand side, you will find a palm tree featuring three distinct trunks and a cluster of leaves. The recipe scroll is hidden behind this palm tree, tucked away in a small crevice right up against the wall.

Crafting Materials:

• Orbit Slime *1
• Icy Slime *1
• Stump Slime *1

Crafting Result: Thorn Slime (Rarity: 1/330K); At Level 1, its stats are 420 HP / 140 Damage.

3. Mushroom Forest (Zone 10) — Geode Slime

Recipe Location: Travel to the far-left edge of the Mushroom Forest Zone (near the border with the Moon Zone) and locate a massive red mushroom. Walk directly beneath the mushroom; look up, and you will see the recipe scroll attached to the mushroom's stalk.

Crafting Materials:

• Ninja Slime *1
• Guest Slime *1
• Aegis Slime *1

Crafting Result: Geode Slime (Rarity: 1/3.11M); At Level 1, its stats are 813 HP / 271 Damage.

4. Redwood Forest (Zone 12) — SlimeSlimeSlime

Recipe Location: After teleporting to the Redwood Forest, make your way to the far-right edge of the map (near the border with the Meteor Zone). Within this zone, locate a thick tree trunk lying on the ground; the recipe scroll is hidden inside the hollow interior of the trunk.

Crafting Materials: SlimeSlime *3

Crafting Result: SlimeSlimeSlime (Rarity: 1/42.9M); At Level 1, its stats are 2020 HP / 676 Damage; a high-rarity Slime intended for late-game progression.

5. Candyland (Zone 14) — Puffy Slime

Recipe Location: Upon entering the Candyland Zone, immediately look to your right to spot three distinct items: an Oreo cookie, a yellow gummy candy, and a chocolate bar. Walk behind the chocolate bar; the recipe scroll is hidden on the back side of the bar. Since the gap between the chocolate bar and the wall is extremely narrow, you may need to adjust your camera angle to catch a glimpse of the scroll.

Crafting Materials:

• Unicorn Slime *1
• Petal Slime *1
• Derpy Slime *1

Crafting Result: Puffy Slime (Rarity: 1/195M). At Lv1, its stats are 4,200 HP / 1,400 Damage.

6. Crystal Cavern (Zone 16) — Astro Slime

Recipe Location: After teleporting to the Crystal Cavern, focus your gaze on the massive stone archway located at the center of the Zone. This marks the highest point in the entire Zone; you must begin climbing from the right side, ascending step-by-step along the ledges until you reach the exact center of the archway's summit—the recipe scroll awaits you there.

Crafting Materials:

• UFO Slime *1
• Bomber Slime *1
• Blackhole Slime *1

Crafting Result: Astro Slime (Rarity: 1/2.47B). At Lv1, its stats are 12,300 HP / 4,100 Damage.

7. Atlantis (Zone 18) — Sunny Slime

• Pumpkin Slime *1
• Ouchy Slime *1
• Ember Slime *1

Crafting Result: Sunny Slime (Rarity: 1/11.8B). At Lv1, its stats are 24,300 HP / 8,100 Damage.

8. Graveyard (Zone 21)

Recipe Location: Follow the path within the Graveyard Zone until you come across a large rock; situated within the adjacent graveyard lies the final recipe scroll currently available in the game.

Crafting Materials:

• Monke Slime *1
• Waxie Slime *1
• Germy Slime *1

Crafting Result: As of now, the name and specific stats of the resulting Slime have yet to be discovered; however, it is expected that players will successfully synthesize it very soon.

The game is still undergoing continuous updates, and new Slimes to synthesize are expected to be added in the future for players to discover. The game's area maps are relatively small; with just a little searching, you should be able to spot the recipe scrolls.

How to Craft Slimes

It is worth noting that there is a chance for the synthesized product to generate as a variant version—specifically the Big, Shiny, Huge, and Inverted types. However, this is only possible if you have already unlocked these specific variants through upgrades:

• Big: 1%
• Shiny: 0.4%
• Huge: 0.1%
• Inverted: 0.04%

Additionally, if you use a material Slime that possesses a special variant attribute during synthesis, it will increase the probability that the final product inherits that specific attribute.

Crafting Tips

Prioritize Unlocking the Teleporter:

For 1 million coins, you can instantly teleport to any Zone you have unlocked. This saves a tremendous amount of time when searching for recipes.

Collect in Zonal Order:

Each recipe appears only within its corresponding specific Zone; you cannot skip ahead. You must unlock them sequentially: Grasslands → Desert → Polar → Volcano → Islands → Cave → Heaven → Jungle → Mushroom Forest → Redwood Forest → Candyland → Crystal Cavern → Atlantis → Graveyard.

Rebirth Does Not Remove Collected Recipes:

Although Rebirth resets your Zone progression, any recipes you have already acquired will remain in your crafting menu, so there is no need to worry.

Collect First, Crafting Later:

Even early-game Slimes—such as the "Crafty Slime"—can provide valuable stat bonuses for your team. Furthermore, gathering the materials required for later-stage syntheses can take some time (as you wait for them to be thrown out). It is recommended that you focus on collecting Crafting recipes first, and then proceed to synthesize once you have gradually gathered all the crafting materials; avoid wasting excessive time trying to farm a single specific material.

Stay Updated:

The game is still undergoing continuous updates; recipes for some of the later zones have not yet been fully confirmed. We recommend keeping an eye on official announcements and update previews.

Purchase Boosts:

Players with the means to do so can purchase various buffs—such as Luck Boosts — from the Slime RNG Shop. These boosts increase the probability of obtaining crafting materials, thereby accelerating your synthesis progress.

Final Thoughts

The crafting system introduces an entirely new dimension of progression to Slime RNG. While some recipes are relatively easy to acquire, gathering the necessary crafting materials can be a time-consuming process. As the game continues to receive updates, it is highly likely that additional recipes and hidden slimes will be introduced in the future, thereby establishing the crafting system as one of the core mechanisms driving long-term player progression.
