If you grew up in the 90s, chances are you remember the thrill of tearing open a tiny packet, pouring mysterious powder into a plastic tank, and waiting with bated breath for your new ‘pets’ to spring to life.
Childhood memories often hold a special place, particularly those associated with unique and imaginative forms of play.
A particular item that captured the fascination of many during a bygone era is now experiencing a resurgence, bringing with it a wave of fond recollection.
Yes, we’re talking about Sea-Monkeys—those quirky, low-maintenance creatures that captured the imagination of a generation.
Well, dust off your nostalgia, because Sea-Monkeys are back on Kmart shelves across Australia, and they’re making a splash with both new fans and seasoned collectors.
A blast from the past
For many of us, Sea-Monkeys were a rite of passage. The anticipation of watching those minuscule brine shrimp hatch and grow was nothing short of magical.
Now, Kmart is giving us the chance to relive those childhood memories—or introduce a new generation to the simple joys of instant pets.
The classic Ocean Zoo Playset is available for just $18, complete with a tank, feeding spoon, three sachets, and easy-to-follow instructions.
If you’re feeling a bit more adventurous, you can even opt for themed tanks like the ‘magic castle’ or ‘Mars’ edition, which come with bonus features such as a water pump and magnifying lid for $22.
Why the Sea-Monkey craze endures
So, what is it about Sea-Monkeys that keeps us coming back? For starters, they’re the ultimate low-commitment pet.
No walks, no vet bills, and no chewed-up slippers. Just a bit of water, a sprinkle of food, and a dash of patience.
They’re also a fantastic way to introduce kids to the basics of biology and responsibility—all without the mess of fur or feathers.
But perhaps the real magic lies in the nostalgia. As one Kmart shopper put it, ‘Just as I remember as a kid.’
Another added, ‘Perfect! Only had for a little while and they’ve hatched, grown and now having babies. Literally so entertaining.’ It seems that, for many, Sea-Monkeys are more than just a toy—they’re a portal back to simpler times.
A brief dive into Sea-Monkey history
The story of Sea-Monkeys begins in 1957, when American inventor Harold von Braunhut spotted brine shrimp being sold as fish food in a pet store.
Sensing an opportunity, he set out to create ‘instant pets’ that could be easily shipped and cared for. After some scientific tinkering, he launched ‘Instant Life’ in 1960—a product that would later be rebranded as Sea-Monkeys.
Initially, sales were sluggish. But von Braunhut had a stroke of marketing genius: he placed ads in comic books, targeting curious kids directly.
The response was overwhelming, and soon Sea-Monkeys were a household name, delighting millions with their oddball charm and ‘miraculous’ hatching process (which, to this day, remains a closely guarded secret).

The science behind the magic
While the packaging might promise ‘instant life’, the reality is a bit more scientific. Sea-Monkeys are a hybrid breed of brine shrimp, known for their ability to survive in a dormant state until conditions are just right.
Add water, and the eggs spring to life, thanks to a carefully balanced mix of salts and nutrients. It’s a fascinating example of nature’s resilience—and a great conversation starter for curious minds.
Tips for Sea-Monkey success
Thinking of bringing home a tank of Sea-Monkeys? Here are a few tips from seasoned fans:
- Don’t use all the eggs at once. Save some for a second batch in case the first try doesn’t go as planned.
- Follow the instructions carefully, especially when it comes to water temperature and feeding.
- Be patient! It can take a few days for the Sea-Monkeys to hatch and become visible.
- Use the magnifying lid to get a closer look at your new aquatic friends—it’s half the fun!

As one parent shared, ‘My daughter saw this on social media and really wanted one. Easy to set up and the monkeys grew faster than expected. Happy child, happy mum.’
Another added, ‘It’s a science project for the kids. Kids are loving the job of feeding the growing Sea-Monkeys.’
