In 1996 a UFO was believed to have crashed in Varginha, Brazil. There were many witnesses, including 3 young girls walking home from work. They seen the entities, describing them as between4 to 5 feet in height, making a strange buzzing sound, similar to the sound of bees. They had 3 rounded protuberances on top of their heads, like that of horns. Oily brownish skin, big redeyes and a strong smell like that of ammonia. Seems it could either be some experimental cross-breeding of an alien entity and Chupacabra.
