‘Christmas Tree' depicts a group of characterful Christmas decorations who come to life and link precariously together in an epic struggle to reach for a box of Celebrations under the Christmas tree. The ad, Mars Celebrations' first in over a decade, mirrors the strapline, ‘Everyone’s Favourite’, by portraying the sometimes extreme lengths people will go to get their hands on their favourite chocolate in the time-honoured collection.
 
Head of Animation, Jorge Montiel explains, "We had to experiment with ways to make the figures look realistic and life-like whilst maintaining a sense of stiffness, staying true to their essence as a decorative object. The facial expressions, therefore, had to be minimalistic, but enough to create a sense of character. A key challenge for the team was that we had to create a sense of adrenaline through the animation, giving an action film flavour to the spot."
