The Ollolai carnival is characterized by the presence of numerous traditional masks: Sos Bumbones. Specifically, SOS Truccos or SOS Turcos, wrapped in a white lace cloth (inghirialettu) once used to cover the foot of the deceased's bed before burial; they wear an embroidered shawl traditionally used to wrap the newborn during baptism (on a blond cape). This clothing has a highly symbolic character. It represents the cycle of life: the death of nature in winter and its rebirth in spring.
Another characteristic mask of the Ollolaese carnival is sa Marizzola, a female figure dressed in a dark red cloth skirt (on Bardellinu), a hand-embroidered white blouse and a particular bodice (sas palas), left visible above the shirt and decorated with gold and silver thread. The garment is covered by a handkerchief embroidered with flowers in relief (on Muccadore Froreau), while a tulle veil or, alternatively, a papier-mâché mask is placed on the face.
The traditional female figures of Maria Vressada, so called because she is wrapped in a bedspread, Maria Ishoppa and Sa Mamm'e and Su Sole represent three scarecrow masks that scare capricious children.
A characteristic male figure, on the other hand, is on Caprarju dressed in a shirt and tight cloth or velvet pants, a white Korean shirt, a cap (on bonette) over which a handkerchief holding a wooden mask is tied, leather boots (sos cambales). The character represents the most agile dancers. Crossed on his chest, he carries a set of small cowbells that ring during dances.
The Truccos, united in groups called sas troppas de harassehare, go from house to house carrying a straw mannequin and old clothes, with their faces made with a cloth on which the eyes and the mouth are drawn (on Ziomu). The puppet hides, under an orbace coat, a bag of sausages and a barrel full of wine (in a group). The puppet, late in the evening, is taken to the outskirts of the town, tried and sentenced to the stake, thus marking the end of the carnival and the beginning of Lent.
Recently, the community of Ollolai has enhanced the carnival tradition by focusing the celebration, parades and stage performances especially in the afternoon hours instead of at night.

The masks
Sos Truccos or SOS Turcos: they are wrapped in a white lace cloth (inghirialettu), they wear an embroidered shawl (on a blond cape) on their shoulders. Their heads and faces are covered with a heavy lace, and they wear a fringed bonnet (capitale'e fronzas).
Sa Marizzola: female figure dressed in a dark red cloth skirt (on bardellinu), a hand-embroidered white blouse and a bodice. On the head a handkerchief embroidered with flowers in relief (on Muccadore Froreau), while on the face a tulle veil or a papier-mâché mask.

The Goat: wears a wooden mask with long horns, a cap, long furs and cowbells. Walk on two cork stools so as not to get contaminated by touching the ground.

History
The Ollolaese carnival officially began on Saint Anthony's day but the actual festivities began on Carnival Sunday, continuing for three days until Ash Wednesday. After Mass, the most relaxed men ready to joke, dressed in the typical masks of the town (on Truccu, sa Marizola, Maria Vressada, Maria Ishoppa, sa Mamm'e and on Sole, on Caprarju) formed the carnival groups (sas troppas de harrasehare), each accompanied by his Bearer, the only member not to wear a mask (he knows carrot or knows visera). Women and children did not disguise themselves even if they participated in pranks and stage performances in the streets of the town. During the three days of festivities, each group visited the homes of its members where a dinner was offered based on roasted pork, sausages, savadas, gathas, cheese and galadina. In the evening the dances continued in the houses or in the square. During the fascist period, starting around 1925, disguises that covered the face were banned. After World War II, masks were readmitted and even women began to dress up. According to tradition, a puppet made of straw and rags carried by a donkey (on Ziomu), containing a barrel of wine and a bag of sausages, accompanied the procession of SOS Intintos, men who smeared their faces with burnt cork, along the streets of the town. Late in the evening on Ash Wednesday, the mannequin was processed and burned.
