The Chunky Triangle Colin
Colin the Caterpillar is one of the most protected assets in the UK grocery landscape. He is a party centrepiece, a national institution, and the subject of a famous supermarket legal dispute. A new design doing the rounds online proposes a significant structural change. A radical reinvention.
The mockup shows a familiar green M&S box, but the cake inside has been crossed with another famous chocolate shape. The ‘Toblerone Chunky Triangle Colin’ keeps the classic white chocolate face and feet. The change is the body. Instead of a smooth milk chocolate cylinder, the caterpillar’s back is a ridged mountain range of nougat-flecked chocolate triangles. It is a direct and clever fusion of two instantly recognisable products.
The Colin Empire
A brand crossover like this feels plausible partly because Colin himself is no longer a standalone product. He is an entire range. The original cake is just the start. He has been miniaturised into M&S Mini Colin the Caterpillar Cakes and deconstructed into M&S Colin the Caterpillar Softies and Speckles.
The brand also covers an extensive line of sweets. The list is long: Colin the Caterpillar Cola Gums, Colin the Caterpillar Sourtastic, Fruit Gums, Sour Stomps, Cherry Gums, and Fruit Sours. There are even Colin the Caterpillar Party Cups and a Party Time mix. The character has proven to be an endlessly adaptable format for M&S. He has already been stretched far beyond his original chocolate-log form.
A Structural Crossover
Most flavour crossovers are simple additions. A biscuit crumb is mixed into a chocolate bar, or a coffee syrup is added to an existing ice cream. This concept is different. It’s a physical alteration. The design merges the fundamental shapes of both products—the caterpillar’s curve and the triangular prism of the Swiss chocolate bar.
Toblerone, a Mondelez brand, has a form as famous as its flavour. The Matterhorn peaks are its defining feature. Transplanting that Alpine silhouette onto the back of a caterpillar from High Street Kensington creates a strange but compelling hybrid. The caption that ran with the image put it plainly: “Toblerone mountain Colin!”.
What the real range looks like
This fictional Toblerone variant would join an enormous real-world M&S range that includes the original M&S Colin the Caterpillar Cake, Mini Colin Cakes, and a wide variety of sweets like Colin the Caterpillar Cola Gums, Softies, Fruit Sours, and Sour Stomps.
