Unstable Goo is a Tier 2 crafting resource in Grounded 2, described in-game as a nasty glowing substance that might explode. You can produce it on demand at the Oven, and you can also pull it straight from certain robotic enemies out in the yard.
Quick answer: Bake Unstable Goo (x3) at the Oven using 1 Spicy Shard, 1 Mint Shard, and 1 Purple Jelly Chunk. If you would rather skip crafting, harvest the remains of O.R.C. Weevils, which drop Unstable Goo at a high rate.
Oven recipe for Unstable Goo
The Oven recipe is the reliable way to make Unstable Goo whenever you need it. Each bake returns three units, so a single batch of ingredients goes a long way.
| Ingredient | Quantity per bake |
|---|---|
| Spicy Shard | 1 |
| Mint Shard | 1 |
| Purple Jelly Chunk | 1 |
| Output | Unstable Goo x3 |
Where to find the crafting ingredients
Two of the three ingredients cluster around the same area, which makes gathering simple. Use the Map screen search filter to mark each material and see every discovered node at once.
Purple Jelly Chunk
Purple Jelly Chunks sit underwater in the Skunk Pond and Gnarly Bark areas. Filtering the Map for “purp” surfaces a spread of these nodes across both regions, so plan an underwater run to scoop them up.
Spicy Shard
Spicy Shards are concentrated in the Ice Cream Cart biome. They show up densely enough there that one trip usually covers your crafting needs.
Mint Shard
Mint Shards also appear in the Ice Cream Cart biome, with a strong presence in the cave underneath it. Because both shards live in the same area, you can grab your Spicy and Mint Shards in a single loop before heading back to the Oven.
Craft Unstable Goo in the Oven
If the Bake option is greyed out, you are missing at least one of the three ingredients. Restock the item that is short and the recipe becomes selectable again.
Harvest Unstable Goo from O.R.C. Weevils
Unstable Goo also drops from O.R.C. Creatures, and O.R.C. Weevils are the most direct source. Defeat one and use the Harvest Remains prompt to collect the goo. The drop rate is high, so clearing a few of them nets several units quickly.
These enemies tend to guard Ranger Outposts, O.R.C. Transmitters, and the Network Center, and areas like the picnic blanket zone hold several at once. They respawn over time, making that spot a repeatable farm whenever you run low.
What Unstable Goo is used for
Unstable Goo feeds into consumables, a trinket, and a couple of furnishings. Stock a small reserve if you plan to craft the Flashfurter or the Volatile Capacitor, since both lean on it.
| Craftable | Type |
|---|---|
| Flashfurter | Projectile / consumable |
| Gooey Glow Stick | Device / consumable |
| Volatile Capacitor | Trinket |
| Pine Wall Lamp | Lighting |
| Pine Chair | Furniture |
Between the Oven recipe and the O.R.C. Weevil drops, you have both a crafted supply and a farmable one. Keep a stack on hand and you will be ready whenever a blueprint calls for that glowing goo.
