Two Confectionery Icons
It’s a crossover that merges two completely different aisles of the supermarket: the celebration cake fridge and the sweet bag hook. This design concept imagines a version of Marks & Spencer’s Colin the Caterpillar decorated with, and presumably flavoured by, Haribo Tangfastics.
The packaging mockup shows the familiar Colin box, but co-branded with the distinctive Haribo and Tangfastics logos. Inside, the usual chocolate-shelled caterpillar is topped not with chocolate buttons or other M&S sweets, but with the iconic sour-dusted gummies from a Tangfastics mix. Cherries, dummies, and crocodiles are all visible on his back, replacing the usual decorations.
The Colin Brand Universe
A sour-themed Colin might seem like a departure, but the core brand has already expanded far beyond the original chocolate log cake. M&S has spent years building Colin into a complete brand identity that now covers a wide range of confectionery and even party supplies. A new flavour variant would simply be the latest in a very long line.
The current product family is huge. Beyond the classic cake and the Mini Colin the Caterpillar Cakes, there is a whole range of bagged sweets. The lineup includes Colin the Caterpillar Softies, Speckles, Cola Gums, Cherry Gums, and Fruit Gums. These products have turned Colin’s face into a brand mark for an entire sweetshop range, sitting alongside other M&S characters.
A Sour Precedent
Crucially, a sour Tangfastics edition wouldn’t even be the first time Colin has ventured into tart territory. The brand already has its own sour sweets, suggesting that M&S sees an appetite for non-chocolate flavour profiles. On shelves right now, you can find Colin the Caterpillar Fruit Sours and Colin the Caterpillar Sour Stomps.
This concept, therefore, doesn’t invent a new flavour direction for the brand so much as propose a collaboration within an existing one. It swaps an in-house sour sweet for a massively famous third-party one. Haribo is a dominant force in UK confectionery, and its Tangfastics sub-brand is one of its most recognisable assets, making this a logical, if fictional, partnership.
What the real range looks like
The current M&S Colin the Caterpillar range extends far beyond the original cake. It includes confectionery like Colin the Caterpillar Softies, Cola Gums, and Cherry Gums. A Tangfastics crossover would sit alongside the brand’s existing sour variants, which include Colin the Caterpillar Sour Stomps and Fruit Sours.
