Remember that craze for dancing babies a few years ago? Now Huggies is letting you can create your very own. What's more, it dances the hula. To promote its new line of Hawaiian-themed diapers, the brand has launched a Facebook app called Hula Baby. Users upload photos of their baby, choose a diaper and create a shareable video. OgilvyOne Chicago and digital agency Luxurious Animals developed the campaign. See a demo below.
