During the festivals of Patum of Berga, simply called La Patum,  and Corpus Christi, the dragon Guita is paraded as an effigy, his visage eroded from the older variations on the European dragon.  Guita protects the inhabitants from evil. To simulate his fiery breath, Guita contains fireworks for its explosive festival appearances. 
Guita is an enormous, serpent-like dragon with a very long neck. Its face is black with large fangs, but the rest of its body is green.
