An anthropomorphic walrus, his schemes always revolve around films and filmmaking. He also has a gang of penguin minions who follow him and do his bidding. One interesting characteristic of his is that he usually plays dumb, pretending that he is either reformed or not doing anything wrong, only to reveal his schemes when the heroes are out of his way.
By his costume and penguin minions, Arturo Tuskerninni is possibly a parody of the Penguin, an enemy of Batman.
His name is a parody of Italian film director Arturo Toscanini.
