Eduard Arnalot, Dudu, begins to perform as a clown in a natural way from a very young age. So, later, to give shape to his inventiveness, he trains with clown and mime professionals, such as Eric de Bont, John Davidson, Moshe Cohen, Johnny Melvine or David Gol, among others. Since 1995, he has worked as a clown and actor for different productions with theatre, clown and circus companies (Cous Cous Clown, Discípulos de Morales, La Fura dels Baus, S'Arruga, Essència de Nit, Unicornis...).

In 2005, he premiered his first individual show, Dudadas, a clownesque gestural theatre show which he toured around numerous theatres in Spain and abroad. In 2010, he premieres Calma, a theatre show, which he represents until 2011, when he is called to take part as Purple Clown in the show Alegría del Cirque du Soleil, with which he has toured all over Europe for two seasons. In 2013 he returns with his street show El niu.
