ZIMPLI Unicorn Surprise Bath Bombs blend collectible toys with bath-time fun

The unicorn bath bomb aisle is still built around one simple pitch: make bath time feel like a reveal. ZIMPLI’s Unicorn Surprise Baff Bombz 3-pack was listed on Amazon UK at £9.99 with a 15% discount, and that price lands well for parents looking for a pocket-money treat rather than a splurge. At roughly £3.33 per bath, the three-pack undercuts the single Large Unicorn Surprise Bath Bomb, which showed about 1,500 customer reviews and a price around £5.66 in one Amazon UK listing.

What makes the product stick is not just the fizz. ZIMPLI says the 3-pack creates a colourful, fizzing bath-time adventure and includes three unicorn figures to collect, with buyers able to hunt for an ultra-rare Gemstone Mermicorn. The wider unicorn line says there are six unicorn figures in total, which turns one bath into part of a larger collecting chase. That toy-surprise mechanic is the real engine here: children get the bath bomb, the fizz, and the payoff of a hidden figure all in one go.

ZIMPLI has built that formula into a much bigger business. The company describes itself as a UK-based maker of fun, innovative bath-time, multi-sensory and educational play products, with a “Just Add Water” approach that is meant to engage children’s senses. Its bath-bomb lineup stretches well beyond unicorns into dinosaur, alien, fruity, Care Bears, Miraculous, Santa, gingerbread and Christmas ducks themes, showing a repeatable format that can be rotated by character, season or gift occasion.

The parent-facing side of the pitch is just as important as the collectible side. ZIMPLI says its Baff Bombz are biodegradable and “skin safe,” “drain safe,” “easy clean” and “stain free,” language that speaks directly to the cleanup worries that can sink a novelty toy at home. Amazon UK’s ZIMPLI store also says the products are endorsed by both the British Skin Foundation and the National Autistic Society, which gives the brand extra credibility in a crowded kids’ bath market.

That sensory angle has mattered before. In February 2024, the National Autistic Society said Zimpli Kids received a Product Approval kitemark for Gelli Play after testing with autistic users and caregivers, with more than 80% of testers saying they enjoyed the smell and feel and 65% saying it helped when they were feeling anxious. Put together, the unicorn bath bombs show why this category keeps winning: they combine a low-cost bath essential with a collectible toy hook, then wrap it in safety, sensory play and easy cleanup.
