Background Information

The Kellogg’s Kombos Campaign: Bringing a cereal mixing activation idea to life

The cereal category faces multiple challenges including declines in penetration and brand repertoire, the loss of occasions to other breakfast options, considerable volume declines as well as other economic and legislative challenges. What if we could find a way to start addressing some of these issues whilst bringing fun and excitement to keep cereal as the undisputed No.1 choice for breakfast?

In the UK, Taste is the no. 1 driver of category growth for cereal, with 75% of consumers saying it is the top priority when choosing breakfast cereal (Mintel report Q3, 2020) and the Kellogg’s cereal portfolio includes an iconic group of great tasting brands (Fig. 1).

Fig. 1 – Overview of the main Kellogg’s UK cereal brands.

At the beginning of 2023, we identified cereal mixing as an area of opportunity for the business. We undertook a data-driven E2E approach, starting with conducting a shopper panel with 500 UK adults (Fig. 2). From this we confirmed that there is indeed a b ig opportunity in cereal mixing, with over half of respondents doing it either on a regular basis or having tried it now and again. We also learned that elevating the eating experience, whether from a flavour or texture perspective, is the key reason why consumers would be motivated to mix different cereal together. Last but not least we identified that within our portfolio of brands that the most taste -led brands like Crunchy Nut and Coco Pops are clear mixing favourites.

Fig. 2 – UK shopper panel results.

We then worked with an agency partner to come up with the ‘What’s Your Kellogg’s Kombo?’ creative platform (Fig. 3), with the objective of launching Kellogg’s ‘Kombos’ as a taste -centric Masterbrand campaign to bring back excitement into the cereal category.

Fig. 3 – What’s Your Kellogg’s Kombo platform visual.

With more clarity on the opportunity around cereal mixing and a work-in-progress platform idea, we then partnered with our Sensory & Culinary team to identify the cereal ‘Kombos’ that could deliver the best eating experience and made a top 10 list including classics like a Coco Pops and Rice Krispies mix (Fig. 4) or a Crunchy Nut and Special K combination.

Page 4

Fig. 4 – Coco Pops & Rice Krispies ‘Kombo’ sensory overview.

Finally, we partnered with our key account teams to commercialize ‘Kombos’, focusing on our core brands and building the individual account plans both in -store and on ecommerce with the aim of delivering a quadruple win: for the category, addressing the aforementioned key challenges around brand repertoire, penetration and value, through a focus on taste; for the customer, delivering a new & different insight - led activation to drive sales; for the shopper, incentivizing an existing habit and delivering on e levated eating experiences and for the Kellogg’s brand, delivering a strong Masterbrand campaign to support our Core product lines and drive volume and repertoire.

The Kellogg’s ‘Kombos’ Campaign In 2023

The campaign kicked off in September 2023 in Tesco and then expanded to other retailers including Sainsbury’s, Morrisons and ASDA throughout October and into November. In parallel with the retailer activity, we’ve also had PR, influencer, sampling and couponing elements of the plan (Fig. 5 – 10).

The Competition Brief for UK Young Lions 2024

Primary objective:

To evolve the ‘Kellogg’s Kombos’ platform and proposition to further drive brand repertoire (e.g., to get someone who currently shops Coco Pops to also add Rice Krispies to their basket) and to consequently drive brand penetration and volume across our top six Kellogg’s cereal brands (Crunchy Nut, Kellogg’s Corn Flakes, Special K, Coco Pops, Rice Krispies and Krave).

Secondary objective:

Reignite excitement for breakfast cereal, doing so in a really fun and taste-centric way.

Additional information:

As mentioned in the background information, 2023 was the first year of this campaign and the key focus was very much in-store so there’s plenty of scope to build upon the idea and/or propose a whole new approach, identifying more opportunities to incentivize the taste -driven UK cereal consumer to mix different Kellogg’s cereals together.

Some potential thoughts on how the Kombos proposition may evolve – note these are purely suggestions and you are not obliged to use them.

  • Is it about heroing certain ‘Kombos’ for certain occasions throughout the year? • Is it about expanding into cereal mixing within other contexts (e.g. cooking/baking) • Is it about establishing cross-category (e.g. milk, fruit) partnerships? • Is it about working with celebrities? • Is it a mix of all the above plus something else?

Your target audience:

The Kellogg’s brand heartland are families. Core audience for this campaign would be 18 -49 adults, given the variety of brands included within it.

Note: whilst the campaign does include kids’ cereal brands (Coco Pops, Rice Krispies), we do not advertise directly to children.

Key messaging

‘What’s Your Kellogg’s Kombo?’ and ‘Mix & Discover the possi’BOWL’ities’ are the two key messages we’ve used for the first year of the campaign. We would like to keep the essence of the messaging consistent for Year Two but are very much open to evolving the message itself.

Tone of voice:

Fun, witty, positive, cheerful, family-friendly. Familiar with a twist. See this advert for reference.

Branding:

Page 9

Please refer to the Assets folder in the Resources section below.

The Kellogg’s Masterbrand logo and the KOMBO logo (which is made up of different letters of the logos of the different cereal brands) must appear in all assets created.

The Masterbrand logo must follow the brand guidelines provided.

The KOMBO logo and its background colour may be redesigned provided all letters are readable and the word spells KOMBO.

Individual cereal brand logos (Crunchy Nut, Coco Pops, Rice Krispies, Corn Flakes, Special K, Krave) may be used dependent on which Kombo(s) is heroed in each asset.

Note: Only the above six cereal brands should feature in your campaign . Any other brands eg. Frosties must not be included.

Note: ‘Mashups’ have been launched in the past in the United States but should not be used in your work as Kellanova would be unable to produce a combination of different cereals as one product, given European supply chain restrictions.

Resources you can access:

Assets folder containing:

  • Kellogg’s Masterbrand logo and guidelines
  • KOMBO logo in its entirety and as individual letters
  • Individual cereal brand logos

Complete creative-brief output from the existing comparison

Campaign Title: “Mix & Discover the possi’BOWL’ities”

Business Problem

Cereal consumption is declining due to shifts in consumer breakfast habits, economic pressures, and increasing competition from alternative options. Kellogg’s needs to revive category relevance and encourage shoppers to expand their cereal repertoire across its core brands.

Human Problem

Breakfast has become boring. People crave excitement, variety, and taste – but their routines keep them stuck in the same bowl.

Audience

  • Primary: UK adults aged 18–49, especially taste-driven shoppers and parents seeking breakfast options that delight the whole household.
  • Secondary: Curious eaters who enjoy playful food experiences and light experimentation (without requiring big changes to routines).

They love:

  • Tasty, familiar flavours
  • A sense of nostalgia and fun
  • Playfulness at the breakfast table
  • Getting value from what they already buy

They want:

  • To rediscover joy and creativity at breakfast
  • Quick ways to elevate the eating experience
  • Permission to mix things up—literally

Insight

People already do mix cereals. They just don’t own it yet. The behavior exists—what’s missing is the brand that celebrates and inspires it.

Single-Minded Proposition

Kellogg’s Kombos: The most playful way to transform your breakfast.

Support / RTBs (Reasons to Believe)

  • Over 50% of shoppers have mixed cereals or are open to it
  • Taste is the #1 driver of cereal choice
  • Kellogg’s portfolio includes iconic, flavour-forward brands with complementary textures and tastes
  • Sensory-tested pairings like Coco Pops + Rice Krispies or Crunchy Nut + Special K deliver exciting, proven experiences
  • Year 1 showed success in-store—consumers *responded* when prompted to mix

Tone of Voice

Cheerful, witty, and family-friendly with a spoonful of surprise. Fun that’s grounded in familiarity.

Action / Mandate for the Creative Team

Bring cereal mixing into the cultural mainstream. Make *“What’s your Kombo?”* a national breakfast ritual by:

  • Turning cereal mixing into a *moment*
  • Giving people reasons to Kombo across different occasions (weekends, seasons, moods)
  • Celebrating top Kombo heroes while inviting personal creativity
  • Inspiring content, social sharing, and in-store conversion
  • Exploring possible extensions: cooking, celebrity endorsements, flavour-based storytelling

Desired Outcome

Shift consumer habits from *buying one box* to *buying two or more* — by showing that mixing isn’t just allowed… it’s encouraged.

Let’s help the UK wake up to a more delicious bowl. Every. Single. Day.

MetaMuse creative brief

Kellogg’s Kombos · Historical creative-brief output

Project: The Breakfast Rebellion

Client: Kellogg's Kombos

Date: 2025-06-17

A brief introduction

In 2023, we lit a small fire with 'Kombos'—we proved people are willing to mix their cereal. It was a successful experiment. Now, it’s time to start an inferno. We’re moving beyond a clever in-store suggestion and aiming for a genuine cultural shift. We’re not just selling two boxes of cereal; we're selling a daily dose of delicious anarchy. This brief isn't about optimizing a promotion; it's about starting a movement from the kitchen counter. Let's give them a reason to tear up the breakfast rulebook.

Objective

To embed cereal mixing into the national psyche, transforming it from a spontaneous novelty into a planned, creative ritual. We will achieve this by driving brand repertoire—compelling shoppers to consciously purchase two different Kellogg's boxes—thereby boosting penetration and volume across our core brands.

Issue

We are fighting a lifetime of conditioning.

For generations, we’ve been told, "Don't play with your food." This unspoken rule has turned the cereal aisle into a place of autopilot, where shoppers grab their one trusted box out of habit. 'Kombos' is currently seen as a fun "hack"—something you do with leftovers, not something you plan for. The idea is a spark in the supermarket aisle that fizzles out before it reaches the breakfast bowl.

Insight

We live to personalize.

We hack our coffee, curate our playlists, and remix our lives to make the mundane magnificent. Yet, our breakfast bowl remains a sacred, untouched territory, governed by that single childhood rule we never thought to question. This isn't about laziness; it's a hidden, universal inhibition. The permission to break this one small rule isn't just about breakfast; it's the key to unlocking a moment of pure, unadulterated creativity before the day has even begun.

The Challenge

Sanction the rebellion against breakfast monotony.

Organizing Idea

Breakfast is better when you play with it.

Who are we talking to?

The Routine Rebels

Picture the 18-49 year-old adult, the parent, the professional. Their life runs on a schedule, a finely tuned machine of responsibility. But inside, there's a spark of mischief. They are the ones who follow a recipe, then add a secret ingredient. They customize their coffee order, their phone case, their game avatar. They find small, low-stakes ways to bend the rules and inject their personality into the everyday. For them, breakfast is a function, not a feeling. They are waiting for a legitimate invitation to turn the most routine moment of their day into a playground.

What is our Tone of Voice?

The Playful Co-conspirator

We are the witty, energetic voice that whispers, "Go on, no one's looking." We don't lecture; we invite. We don't prescribe; we celebrate their genius.

  • Playful: We actively encourage mischief and celebrate the simple joy of creation.
  • Witty: Our humour is clever but never alienating. We live for a good pun ('possi'BOWL'ities') and share an inside joke with our audience.
  • Enthusiastic: Our energy is infectious. We are genuinely psyched about the endless combinations, turning a pantry into a creator's palette.
  • Encouraging: There are no wrong answers here. Every Kombo is a masterpiece. We are the hype-person for their 7 AM culinary alchemy.

The Nuts & Bolts

Key Message & Tagline:

The platform is "What's Your Kellogg's Kombo?".

The tagline has been "Mix & Discover the possi'BOWL'ities".

We want to retain the spirit of this, but you have full creative license to evolve the language to fuel the rebellion.

Mandatory Branding:

The Kellogg's Masterbrand logo MUST appear in all assets, following brand guidelines.

The KOMBO logo (made of different cereal brand letters) MUST appear in all assets. You may redesign its background, but the word must remain clear.

The Hero Brands (The ONLY brands to feature):

  • Crunchy Nut
  • Kellogg's Corn Flakes
  • Special K
  • Coco Pops
  • Rice Krispies
  • Krave

Mandatory Exclusions & Rules:

  • Absolutely no other Kellogg's brands (e.g., Frosties).
  • We do not advertise directly to children. The campaign must be targeted at adults (18-49).
  • We cannot produce a "Mashup" product (two cereals in one box) due to supply chain constraints. The campaign must focus on buying two separate boxes.

Deliverables & Media:

We are looking for a big, integrated, full-funnel campaign idea.

Assume all channels are on the table: TV/VOD, Social, Digital, OOH, PR, Influencer, Shopper Marketing/POS. We need an idea that can ignite a conversation and translate into action at the shelf.

Budget & Timeline:

Budget is TBD and should be guided by the ambition of the idea.

The campaign is planned for execution in the latter half of 2025.

The final output should not feel like an ad. It should feel like a testament.
