He is based in Sergio Busquets. His name is a pun on Busquets, making Buckets and that's because he has a bucket as his body.
He had a minor appearence in the Champions League 2014/15 Final Barcelona X Juventus. In that game he is hit by Vidal. He, along with the whole Bancelona squad, won this game and the League. At that time, we could only see his back.
His first speaking role comes in Barcelona vs Atletico Madrid 1-1 (Goals, Highlights, Red Cards +more!)(Copa Del Rey 2017 Semi-Final) where he asks the referee if he could kick the ball. The ref angrily replies "No!" and Buckets still kicks the ball where he is then yellow carded for.
