A High-Profile Crossover
Two of the UK’s most recognisable confectionery brands appear to collide in this new design. The concept places the familiar hazelnut cream and crisp wafer of a Kinder Bueno White inside the classic chocolate log format of an M&S Colin the Caterpillar cake. The mockup proposes a complete flavour takeover, swapping Colin’s milk chocolate shell for white chocolate and decorating his back with segments of a real Kinder Bueno White bar.
The packaging adopts the established M&S Colin branding, but integrates the clean red and white design of the Kinder Bueno range. Even the signature Colin the Caterpillar font is rendered in Kinder’s specific shade of red. The caption that accompanied the image online reads: “Kinder Bueno White Colin the Caterpillar! White chocolate and hazelnut heaven, who’s getting a slice of this?”
The Colin Franchise
Colin the Caterpillar has long since expanded beyond his original cake form. He is a full-blown M&S sub-brand, a franchise that now covers a wide shelf of products, most of them sweets. The confectionery line-up is extensive, including Colin the Caterpillar Softies, Fruit Gums, Cola Gums, and Cherry Gums. More recent additions have focused on sour flavours, such as the Sourtastic mix, Sour Stomps, and Fruit Sours.
Aside from the main celebration cake and the Mini Colin the Caterpillar Cakes, the character also appears on partyware like Party Cups and in Party Time selection boxes. While the brand has experimented with seasonal variations for Halloween or Christmas, a direct flavour crossover with an external confectionery brand like Kinder would be a new direction. It would move the character out of the M&S own-brand ecosystem for the first time.
A Party Staple Reimagined
For decades, the Colin the Caterpillar cake has been a non-negotiable centrepiece for British birthdays, office leaving parties, and miscellaneous celebrations. Its simple appeal – a chocolate sponge roll with chocolate buttercream, covered in a milk chocolate shell with a solid white chocolate face – has made it an institution. Its status is so secure that any proposed change to the formula is guaranteed to get attention.
Kinder Bueno, meanwhile, has its own distinct identity. It is not a solid chocolate bar, but a multi-textured one, defined by the thin, crisp wafer shell filled with a smooth hazelnut cream. This mockup suggests a direct translation of that experience into a sponge cake, promising the same flavour profile in a shareable party format. The combination taps into the core strengths of two very different, but equally popular, products.
What the real range looks like
The actual M&S Colin the Caterpillar range is extensive, covering the original cake, Mini Colin Cakes, and a wide variety of sweets like Cola Gums, Cherry Gums, Softies, and Sour Stomps. A brand crossover flavour like Kinder Bueno White would be a completely new type of product for the Colin lineup.
