Two Icons Combined
This design unites two deeply familiar UK brands: M&S’s Colin the Caterpillar and the Tunnock’s Teacake. One is the default cake for millions of British office birthdays. The other is a dome of Italian meringue on a biscuit base, sealed in a thin chocolate shell and wrapped in distinctive red and silver foil.
The mockup proposes a direct fusion. The standard Colin sponge roll is reimagined with a white chocolate coating and a face to match. The box abandons Colin’s usual green branding for the iconic Tunnock’s foil pattern, instantly signalling the collaboration. It’s a simple visual idea that borrows the identity of one product and applies it directly to the format of another.
The Colin the Caterpillar Range
The core Colin the Caterpillar cake has spawned a vast ecosystem of spin-off products. M&S has expanded the brand well beyond the original chocolate log cake, creating an entire category in its food halls. The range now includes smaller versions like the M&S Mini Colin the Caterpillar Cakes and M&S Colin the Caterpillar Softies, which are individual sponge roll slices.
Confectionery is the brand’s largest extension. The sweets aisle now contains M&S Colin the Caterpillar Speckles, Cola Gums, Fruit Gums, Cherry Gums, and multiple sour varieties including Fruit Sours and Sour Stomps. The intellectual property is even licensed for non-edible goods like M&S Colin the Caterpillar Party Cups and Paper Plates, cementing its status as a party-planning staple. This consistent expansion into new formats makes the idea of a flavour collaboration feel like a logical next step.
A Question of Filling
A standard Colin the Caterpillar is a straightforward affair: a chocolate sponge roll with a chocolate buttercream filling, coated in milk chocolate. It is decorated with sugar-coated chocolate beans, with a solid white chocolate face and feet.
A Tunnock’s Teacake has no sponge or buttercream. Its primary component is the light, marshmallow-like meringue filling. A true hybrid would presumably need to substitute Colin’s buttercream for this signature mallow, creating a completely different internal texture. The biscuit base of a Teacake would also need to be incorporated, perhaps as crunchy pieces within the filling or as a replacement for the chocolate feet. This crossover would require a significant change to the fundamental Colin formula.
What the real range looks like
The current M&S Colin the Caterpillar range is extensive, covering the original cake, Mini Cakes, Softies, and a huge selection of confectionery like Cola Gums, Fruit Sours and Speckles. A brand crossover like this Tunnock’s Teacake version would be a new development, sitting alongside the main cake as a major special edition.

Frequently asked questions

- Has Colin the Caterpillar had other official brand collaborations?
- No. While M&S releases numerous seasonal and special editions of Colin for events like Halloween, Christmas, and Easter, these have been variations on the core product rather than official co-branded crossovers with other food manufacturers.
- Is the Tunnock’s Teacake Colin the Caterpillar real?
- No, this product does not exist. It is a Snackfish — a fictional food concept and digital mockup created by the online page UK Snack Attack. It is not available for purchase in M&S or any other shops.
