Lush’s Yoshi Egg bath bomb hides a collectible surprise inside the fizz
Lush’s Yoshi Egg bath bomb turns the reveal into the product, hiding one of four collectible shower gummies inside, including a Fire Flower that dyes the tub red.
The real hook is not the fizz. It is the moment the Yoshi Egg bath bomb cracks open in the tub and reveals one of four collectible shower gummies, with the Fire Flower version turning bathwater a startling red.
Lush built the Yoshi Egg Bath Bomb as part of The Super Mario Galaxy Movie × Lush, a limited-edition collaboration with Nintendo and Illumination. The company says the release was made to celebrate the film, which was slated to reach cinemas on April 2, 2026, and to push the experience past a standard bath bomb into something closer to a fandom unboxing.
That is the smart part of the design. Lush’s product copy says you do not find out what is inside until the egg is launched into the tub, which makes the whole thing feel like a reveal rather than a purchase. Each hidden gummy comes with a blend of essential oils and skin-softening carrageenan, so the collectible angle is not just sitting on top of the self-care angle. It is built into it. In a category where most bath bombs promise scent, color and maybe a little sparkle, this one adds suspense.
The Fire Flower is the one that will travel best online. A bright red tub reads less like a spa soak and more like a special-effect shot, which is exactly why the reaction around it feels bigger than a single product drop. Parents, fans and casual viewers are likely to see the same thing differently: a playful Mario tie-in, a collector’s prize, or a bath that suddenly looks intense enough to spark debate. That tension is part of the appeal, because the most shareable bath bombs are rarely the quiet ones.
Lush knows that formula. The company says collaborations have long been part of its business, used to reach new audiences and create experiences, and the Yoshi Egg fits that strategy cleanly. It gives collectors a reason to hunt the drop, gives Mario fans something to show off, and gives the bath bomb aisle a reminder that the loudest products are often the ones hiding something inside the fizz.
