You're running around Rainbow Island, vacuuming up every Cotton Slit and Jellystone in sight, and suddenly your inventory is full. Again. It sucks. We’ve all been there, staring at a pile of glowing ores we can't carry because our vac pack is basically a glorified grocery bag. To fix this, you need the storage cell Slime Rancher 2 uses to unlock those sweet, sweet inventory expansions. But here’s the thing: the game doesn't just hand them to you on a silver platter. You have to hunt.
Most players think they can just stumble upon the blueprint by vacuuming random crates. While crates are great for resources, the Storage Cell is a specific Treasure Pod item. If you aren't looking in the right nooks and crannies of Ember Valley, you’re going to be stuck with a puny inventory for a long time. It's frustrating. It's tedious. But once you get it, the game fundamentally changes.
Where the Storage Cell Slime Rancher 2 Blueprint is Actually Hiding
You need to head to Ember Valley. If you haven't unlocked it yet, you've got to pop the Pink Gordo in the north of Rainbow Fields to find the teleporter. Once you're in the volcanic, teal-colored chaos of Ember Valley, the real search begins.
The storage cell Slime Rancher 2 blueprint is tucked away in a Treasure Pod located in the northern region of Ember Valley. Look for a cave system near the area where Crystal Slimes and Boom Slimes like to hang out. There’s a specific ledge hidden behind some rock pillars. Honestly, if you aren't looking up, you’ll miss it. The pod is blue. Pop it open, and the blueprint is yours.
Don't celebrate too early, though. Getting the blueprint is only half the battle. Now you have to actually build the thing at the Fabricator in your basement.

What You’ll Need to Craft It
The Fabricator is a hungry beast. For the first Storage Cell upgrade, which bumps your slot capacity from 20 to 30, you're going to need a specific shopping list of resources.
First, grab 450 Newbucks. That’s the easy part. Just sell some Tabby or Rock plorts. Next, you need 10 Rock Plorts. Again, simple. But then comes the real work: 3 Jellystone.
Jellystone is found in the rocky outcroppings of Rainbow Fields. It looks like a lumpy, purple-ish rock sticking out of the walls. You need the Resource Harvester upgrade to collect it. If you haven't upgraded your vac to suck up science materials yet, you're dead in the water. Go do that first.
Why the Storage Cell is a Non-Negotiable Upgrade
You might think, "Eh, I can just make two trips." No. You can't. Not when you're deep in Starlight Strand and you find a Flutter Gordo or a rare nectar deposit.

The storage cell Slime Rancher 2 provides is about efficiency. The game world is significantly larger than the first game. The distances between your home base (The Conservatory) and the far reaches of the maps are long. Walking back and forth because you ran out of room for Radiant Ore is a massive time sink.
Later upgrades require even more Storage Cells. We’re talking about carrying 40, 50, or even 60 items per slot. To get those, you’ll eventually need more complex materials like Lava Dust and Diamond, which only appear in later-game areas or through specific slime science drills.
Common Mistakes When Hunting for Pods
A lot of people get turned around in the caves. Ember Valley is vertical. If you're just walking on the ground, you're missing 60% of the loot. Use your jetpack. Seriously.
Another tip: listen. Treasure Pods make a very distinct, low-frequency humming sound. If you hear a "wom-wom-wom" noise through your headphones, stop. Look behind the waterfalls. Look on top of the high pillars. The developers at Monomi Park love hiding these things in plain sight but just out of your normal field of vision.

The Science of Efficiency
Once you have that first storage cell Slime Rancher 2 upgrade, your gameplay loop shifts. You stop being a scavenger and start being a strategist.
- Prioritize Radiant Ore: You’ll need this for the Jetpack drive.
- Keep Jellystone on Hand: It's the "wood and stone" of this game; you'll use it for almost every early gadget.
- Don't Ignore the Refinery: Your storage cells only work if you have a way to process the materials you find. Build Refinery Links in the field so you don't have to carry the raw materials all the way home.
The Path Forward for Your Vac Pack
After the first cell, keep your eyes peeled for the Tank Liner and the Power Core. A big inventory is useless if you run out of energy and fall into the Slime Sea, losing everything you just gathered. It’s a delicate balance of carry capacity, mobility, and survivability.
Most veteran players aim for the "Extra Tank" upgrades immediately after the Storage Cell. This allows you to carry more types of items, while the storage cell allows you to carry more of each item. Using them together is how you turn Beatrix LeBeau into a resource-gathering machine.
Immediate Actions for Your Next Session
Stop what you're doing. Check your Fabricator. If you don't have the Storage Cell unlocked, mark Ember Valley on your mental map.
- Check your Harvester: Ensure you have the upgrade to suck up ores and stones.
- Farm 10 Rock Plorts: Keep them in your silo so you don't accidentally sell them.
- Head to Northern Ember Valley: Look for the blue Treasure Pod near the volcanic vents.
- Mine 3 Jellystone: Look in the starting area (Rainbow Fields) for the purple nodes.
- Craft and Conquer: Get back to the lab and install that cell.
Getting your inventory space sorted is the single biggest "quality of life" improvement in the game. It turns the chore of inventory management back into the joy of exploration. Once those slots jump from 20 to 30, the island feels a lot smaller, and your possibilities feel a lot bigger.
