If you were the game master, what challenge would you like to throw to Ranbir?
Well,any game or a challenge is designed keeping in mind certains conditions :
the game master;
the contestant(Ranbir);
the product(Pepsi); and
a three tier link between the above three which makes a perfect formula for success
The challenge should be such that it :

is interesting

Challenge
Beach Challenge.To spot twin - dolphins [ usually dolphins travel in groups.However there are certain who travel in pairs only.Spotting them is a tough thing to do ]
Ranbir would require to follow them ,both, which in turn guide and lead him too a hidden treasure of "Pepsi".
It's not easy.The dolphin's too like Pepsi and it would take certain skills - [ singing a song , playing with them, giving them a product similar to Pepsi [ a competitiors ,may be ] which the Dolphin refuse .
The entire theme of making up to the Dolphin in return of the hidden treasure would serve a strategic purpose.
People love dolphin's . They are simply cute. So is Ranbir.
The color of water and the entire theme matches with Pepsi's base color - Blue.
Blue also symbolizes: youth, spirituality, truth and peace. All these , which the generations of today "youngistaan" looks up to.
Presenting such a challenge is something which all can watch and the "word-of-mouth" in such things is great for a higher brand recall.
There are of course modifications possible.However if you imagine an entire picture of the challenge being performed by Ranbir , I am sure you will be left with a smile and a desire to grab a Pepsi right away.
