How Blob Stack Came to Life

Some of our designs begin with a very clear concept.

Others happen almost by accident.

Blob Stack belongs to the second kind.

Before Blob Stack existed, we had already created quite a few members of what we jokingly think of as our slime family.

*Blob Stack didn't appear out of nowhere. It grew out of our ever-expanding slime family.

It started with Jellybean Paws — a simple, straight-shaped design inspired by a little blob of slime with a smiling cat face and tiny paw pads. It was designed to be approachable and beginner-friendly, with XS and S sizes.

Then came Shadow Paws, a longer and more mischievous evolution of the idea, with a darker expression and a choice of S, M, and L sizes.

And somewhere along the way, we also created Neko Puff — a tiny, rounded cat-like blob that almost looks like a slime that decided to turn itself into a little ball.

Then came Jellybean Critters.

Instead of making one large toy, we imagined what might happen if a slime swallowed one of our fantasy designs and transformed into a tiny creature carrying its features.

That gave us a whole little family of critters.

And then, one day, one of our team members stacked a few Neko Puffs together.

Our designer saw them and asked:

“What would happen if a bunch of slimes were stacked together?”

A rough sketch followed.

And somehow, it was immediately adorable.

That was the beginning of Blob Stack.

*Sometimes, the best ideas start with something as simple as stacking a few cute things together.

 

From Slimes to Little Creatures

The original idea was simple:

Slimes stacked together.

But when we turned the sketch into an actual model, something unexpected happened.

Each blob started to look like a different little creature.

One might look like a cat.

Another might look like a puppy.

Another could be a rabbit, a tiny pig, or something that doesn't quite belong to any species we know.

Even our designer couldn't clearly define what each one was supposed to be.

And we decided that was probably a good thing.

Instead of telling everyone exactly what these creatures are, we wanted to leave some room for imagination.

Maybe they're little slimes.

Maybe they're animals.

Maybe they're something that doesn't have a name yet.

You get to decide.

There Was No Blueprint for the Blobs

Unlike some of our more structured designs, Blob Stack wasn't created by carefully designing every creature one by one.

Our designer approached the model almost like sculpting with clay — simply following the shapes that felt cute and interesting.

That's why every blob has its own little personality.

The grassy base and tiny flowers came later, when we were finishing the bottom of the design.

Once we added them, the whole scene suddenly felt like a group of tiny creatures playing together on a patch of grass...

...and somehow ending up in a very cute pile.

More Than a Dozen Color Experiments

The model came together relatively quickly.

Choosing its colors was a completely different story.

We experimented with more than a dozen different colorations and effects.

We started simple: solid colors, then metallic finishes.

From there, we moved into two-color gradients — one opaque color fading into another, translucent fading into semi-translucent, and different combinations of opacity and saturation.

Then we tried three-color gradients.

And eventually, rainbow.

Some of the combinations were ones we already suspected wouldn't work.

But we made them anyway.

Because sometimes a coloration that looks strange in your head becomes surprisingly beautiful once you see it on the actual model.

And sometimes the opposite happens.

Why We Wanted Green

One thing became obvious very quickly:

Blob Stack looked incredibly cute in pastel colors.

But we've already made a lot of pink, purple, and blue toys.

We wanted Blob Stack to bring something new to our collection.

So we decided:

We had to make a green coloration.

Our first idea was a simple yellow-to-green gradient.

We tried several versions with different saturation, brightness, and warm/cool tones.

None of them felt quite right.

Then one of our team members suggested:

“What if we put white between the yellow and green?”

That small change completely transformed the color.

Suddenly, it reminded us of fresh leaves, new grass, and tiny green shoots appearing at the beginning of spring.

And that's how Spring Sprout was born.

 

A Little Something From the Sea

For the second coloration, we wanted to move in a completely different direction.

Instead of another cute pastel gradient, we wanted something a little more mysterious.

Something that felt almost like a treasure recovered from the sea.

We experimented with a shell-like pearlescent finish, giving the silicone a soft, iridescent quality.

It does obscure some of the tiny details of the model.

But that became part of its charm.

It looked like something that might have been discovered beneath shallow water — perhaps a strange little creature that had been living among shells and coral.

That's how Shallow Bloom found its way into the final three.

And Then There Was Rainbow

Rainbow was surprisingly easy.

From the beginning, we felt that a rainbow gradient simply belonged on this model.

Each blob could carry a different color.

And suddenly, you could see the structure of the design even more clearly:

This isn't one creature.

It's a whole bunch of little creatures stacked together.

When we poured the final version, we even paid attention to where the colors changed.

We tried to position the transitions around the boundaries between the blobs, rather than having a color change run directly across one creature's face.

The result felt almost too perfect for the design.

And judging from the reaction when we shared the final colorations, we weren't the only ones who thought so.

Three Colorations, Three Different Worlds

Eventually, we narrowed all those experiments down to three.

Spring Sprout brings the feeling of spring and nature — fresh, soft, and full of new growth.

Shallow Bloom takes Blob Stack somewhere more mysterious, with a shell-like, underwater treasure aesthetic.

And Rainbow is pure playful chaos — colorful, cheerful, and almost like a pile of ice cream scoops or macarons.

The rejected colorations weren't necessarily bad.

Some of them were actually beautiful.

They simply didn't feel like Blob Stack.

Rather than letting those experimental pieces disappear, many of them will eventually make their way into our Monthly Drops, where they can wait for someone who sees exactly what makes them special.

Why Rainbow Works So Well

When we first showed the final colorations to our community, Rainbow quickly became one of the favorites.

And we think we know why.

Because every color naturally settles on a different blob, the rainbow makes the structure of the model immediately obvious.

You can almost see the individual creatures separating from one another.

It turns the coloration into part of the storytelling.

And honestly, we had already imagined Blob Stack in rainbow before we even finished the model.

Some designs just seem to tell you what color they want to be.

How Did We Come Up With the Name “Blob Stack”?

This part was actually a little more complicated than it sounds.

At first, we were thinking about names connected to slime and the idea of a tower.

Then, around the same time, we posted a silhouette teaser and asked our community to guess what the new design was.

People guessed all kinds of things:

Cake stack.

Ice cream.

Silly critters stacked together.

And suddenly, we realized something.

Why were we limiting the design to being “slime”?

The model could be interpreted in so many different ways.

And the word “tower” didn't quite feel right either.

A tower sounds architectural and rigid.

This wasn't a tower.

It was a soft, wobbly pile of little things that happened to be stacked together.

So we started thinking about words that captured that feeling.

And eventually, Blob Stack just clicked.

It was simple.

It described the shape.

And, most importantly, it left the creatures open to interpretation.

Why Is Blob Stack Beginner-Friendly?

We wanted Blob Stack to be approachable from the beginning.

One reason was size.

We currently only have a few designs available in XS, and some of our existing XS models have already been around for quite a while. It felt like the right time to give beginners another option.

Blob Stack gradually increases in size from top to bottom, so even the smaller sizes can create a surprisingly full sensation without starting with a large diameter.

Its rounded shape also makes the overall silhouette feel less intimidating than many traditional fantasy designs.

And then there's the firmness.

We chose a relatively soft firmness that works not only for use, but also for simply picking it up, squeezing it, and playing with it.

That's something we really like about Blob Stack.

You don't necessarily have to think of it as a traditional fantasy toy.

It can simply be...

a ridiculously cute pile of little creatures sitting on your desk.

Even if you didn't know what it was made for, you'd probably still want to pick it up.

And if you're curious about the larger sizes, we'd love to hear from you.

Would you want to see Blob Stack in L or XL someday?

A Little Secret From the Studio

And since we're talking about the evolution of our slime family, we might as well share one little secret.

Serenity Paws is still under construction.

It will be the softer, rounder counterpart to Shadow Paws — and yes, we're currently imagining something shorter and chunkier.

We can't promise when it will arrive.

But apparently, the slime family isn't finished growing yet.

Blob Stack Is Yours to Interpret

Perhaps the most important thing we learned while making Blob Stack is that we don't always need to define everything.

We could tell you exactly what every blob is.

We could give each one a name, a personality, and a story.

But maybe it's more fun if we don't.

Maybe the one on top is a cat.

Maybe the one underneath is a puppy.

Maybe they're all mysterious little slimes.

Or maybe they're something that doesn't exist anywhere else.

There's no wrong answer.

After all, it's your little stack of blobs.
