Cadbury Creme Egg: When Will It Goo

Cadbury, along with agency MCsquared Dublin, created an integrated campaign that enlisted the Irish public to help their giant Creme Egg release its Goo. Here, “Goo” is the campaign’s shorthand for the public release moment.

Eight rocking giant eggs, each protected in a transparent case, were placed around Dublin. Fans were asked to tweet “Goo” using #tweet2goo or enter via the campaign Facebook app. Every tweet and Facebook post made the egg get more “egg-cited” until it “egg-sploded”.

The entire Goo event was broadcast live on the Cadbury Ireland Facebook page, and participants were automatically entered into a draw to win tickets to the London 2012 Olympic Games.

From social input to physical payoff

The mechanic is a simple loop with a strong public proof moment. People post. The installation reacts. The reaction builds suspense. Then the payoff happens in public, with a clear “we did that” feeling for anyone who participated.

In Irish FMCG launches where seasonal products rely on impulse and talk value, turning participation into a shared street spectacle can earn attention that paid media cannot easily buy.

Why it lands

This works because it turns a familiar product truth, the goo, into a shared mission. Because people can see progress building toward a public release, each post feels consequential rather than disposable. The spectacle turns remote social actions into something you can physically witness, and the ticking progress effect gives people a reason to keep posting and to pull friends in. The live broadcast also gives the event a second stage, so even people not in Dublin can follow along and contribute.

Extractable takeaway: If you want social participation at scale, design a public system where every small action visibly moves a shared object toward an inevitable moment. The promise of that moment does the acquisition work.

What the campaign is really buying

It is not just awareness. It is repeat behavior during a short seasonal window. The real question is how to turn a short seasonal sales window into repeat participation instead of one-off attention. The hashtag and the Facebook entry mechanic reward persistence, and the prize draw adds a practical reason to participate even if you are not nearby.

What to steal for seasonal participation campaigns

  • Make the participation rule obvious. One hashtag, one word, one job.
  • Translate digital actions into physical feedback. That is what creates credibility and excitement.
  • Build suspense, not just a reveal. Progress is a stronger engine than surprise.
  • Give it two stages. Street spectacle plus a live stream extends the audience.
  • Add a lightweight incentive. A draw works best when the core experience is already fun.

A few fast answers before you act

What is “When Will It Goo”?

A Cadbury Creme Egg activation where tweets and Facebook entries drive giant public eggs toward a live “goo-splosion” moment.

Why does the physical installation matter?

It turns online participation into something visible and real, which increases belief, excitement, and sharing.

What is the role of the hashtag?

It is the simplest participation interface. It makes the action easy to repeat and easy to recruit others into.

What is the biggest execution risk?

If the installation feedback is slow, unclear, or unreliable, people stop participating because they cannot see impact.

How can a smaller brand replicate the pattern?

Use one shared object, one simple input, and one visible progress signal. The object can be smaller, but the loop must stay legible.

Budweiser: Ice Cold Index

Weather obsession turned into a price lever

Few cultural triggers are as universal as the weather. Budweiser used that everyday obsession to turn attention into action at the pub.

Irish people have always been fascinated by the weather, but their interest is set to reach new heights this summer with the launch of the Budweiser Ice Cold Index.

The Budweiser Ice Cold Index app is set to show you the local weather, then spit out redemption codes for free or discounted beer at nearby participating pubs. The higher the temperature, the less you will pay for your pint.

How the Ice Cold Index mechanic worked

The mechanism is simple. Combine three inputs into one immediate reward: location, temperature, and a redeemable code.

The app checks local weather. It then generates a redemption code tied to nearby participating pubs. Price sensitivity is built into the rule set. As temperature rises, the customer’s price drops. This is dynamic pricing in its simplest form: a discount rule that updates automatically based on a measurable condition.

That turns “checking the weather” into “moving into the selling space”.

The real question is how you turn a daily habit check into a measurable step toward purchase without it feeling like a random coupon drop.

Linking price to an external context signal beats arbitrary discounting, because the offer explains itself in one line.

In Irish on-trade activations, weather-linked rules can make a pub choice feel like a natural, talkable next step.

Why the offer feels timely, not forced

It lands because it connects to a real moment of intent. Warm weather increases thirst and increases pub footfall. The offer arrives at exactly the time the customer is already considering a drink.

Extractable takeaway: If you can anchor an incentive to a shared, observable condition, you reduce explanation friction and increase redemption because the context does the persuading.

It also feels fair and transparent. The rule is easy to understand. Hotter day equals cheaper pint. That clarity reduces skepticism and makes the incentive feel like a natural extension of the context.

The business intent behind linking price to temperature

The intent is to convert ambient interest into measurable behavior.

By tying discounts to local conditions, the brand creates a reason to choose a participating pub now, not later. It also encourages repeat checking and repeat visits, which is where loyalty accrues in practice.

This app literally moves people into the selling space, provides refreshment, and so it should gain some loyalty points with customers as well. Too bad it is only in Ireland.

Steal these moves from the Ice Cold Index

  • Attach the incentive to a context signal. Weather is a shared trigger that makes offers feel relevant.
  • Use a rule people can explain in one sentence. Clarity increases trust and redemption.
  • Move people into the selling space. The best mobile incentives reduce distance between intent and purchase.
  • Design for repeat behavior. If the offer updates with conditions, customers have a reason to come back.

A few fast answers before you act

What is the Budweiser Ice Cold Index?

A mobile app concept that shows local weather and generates redemption codes for discounted drinks at nearby participating pubs, with discounts increasing as temperature rises.

What was the core mechanism?

Dynamic pricing driven by weather conditions, delivered through location-aware redemption codes for nearby pubs.

Why does tying price to temperature work?

Because it aligns with real-world demand. When it is warmer, people are more likely to buy a cold drink, and the offer feels timely rather than random.

What business goal does this support?

Driving footfall to participating pubs, increasing redemption rates, and encouraging repeat engagement through an offer that changes with conditions.

What is the transferable takeaway?

Use a shared context trigger to make incentives feel natural, then deliver a simple, redeemable action that moves people into purchase.
