Brazil's Zombie Walk celebrants shuffled down the streets of Brazil's major cities on Wednesday to commemorate All Soul's Day -- also known as the Day of the Dead.
It's one of several zombie-themed events that happen every year in Brazil.
People dressed as zombies participated in the walk in Sao Paulo, Brazil on November 2, and hundreds of people hit the streets of Rio de Janeiro in their zombie best.
Wait, what's the Day of the Dead?
Dia de los Muertos is a traditional celebration that originated in central and southern Mexico, the last of a three-day Catholic holiday that starts with All Hallow's Eve (Halloween) on October 31, All Saints Day on Nov. 1 and All Souls Day on Nov. 2.
Families typically celebrate Dia de los Muertos by visiting the graves of family members and ancestors. Scholars trace the origins of the holiday to an Aztec festival later adopted by the church.
