Curupira

A curupira is a red-haired, forest-dwelling dwarf native to Brazil. They are fiercely protective of any other magical creature and will defend them when they feel they are being harmed by humans. The feet of the curupiras face backwards relative to their bodies.

History
A group of curupiras are used as the mascot for the Brazilian National Quidditch team. During the opening ceremony of the 2014 Quidditch World Cup, the curupiras believed that the handlers attempting to stop a fight between the Fijian Dukuwaqa and Norwegian Selma were hurting the creatures and thus attacked, adding to the already extreme chaos and bloodshed.
