The Baurú Incident

 It was July 23rd of 1947, and a group of surveyors were working in the countryside near Baurú in the Brazilian state of Sao Paulo when they became aware of a loud whistling noise before noticing the sudden arrival of a saucer-shaped craft. All but one of them, José C Higgins, fled the scene in terror. This is his story.

UFO Contact from Uranus 

Higgins, a topographer, watched the object descend. It was a lens-shaped craft with a surrounding flange, and was roughly 150ft in diameter with a 3ft rim and a height of 15ft, according to one source. Its body was 'crossed by tubes in several directions', and it was from said tubes that the whistling sound emanated. The UFO landed about 150ft away from the terrified topographer, and appeared to be supported by four metallic struts that seemed to bend a little.

A beautiful sci-fi depiction of the incident

His curiosity got the better of him as he walked towards the anomalous aircraft, and saw a black glass window on the craft from which two humanoid shapes seemed to be watching him. A door opened beneath the rim of the object and three entities of about 2.15 meters (7ft) in height emerged. They were wearing inflated transparent suits which covered their bodies like 'plastic bags', and there were metal boxes affixed to their backs. Beneath the bubble-like spacesuits, the creatures are visibly clad in colourful shirts and shorts which appeared to be made of paper as opposed to cloth. Their heads lacked eyebrows or any other hair, and their eyes were described as being large and round. Their legs were said to be proportionately larger than those of a human, and all three of the entities appeared to be identical. Higgins couldn't tell if they were male or female, but he claimed that they had 'a certain beauty' about them.

The entities spoke amongst themselves in an unknown language, and Higgins noticed that they chose to remain entirely in the shade except for some very brief periods. One of them pointed a tube-shaped object at him and motioned for him to enter the door of their odd aircraft. Through this door he could see another, inner door and the end of a 'pipe' which was presumably some kind of corridor.

Higgins presumably decided to try and learn something from his unique situation, and so somehow asked the entities where they came from using gestures. All the sources concur that this was what he did - how on earth (or any other planet for that matter) he did it I have no idea. On the ground, one of the aliens drew a dot surrounded by seven circles. The dot was apparently supposed to represent the Sun - which the beings referred to as 'Alamo' in their language. They pointed to the seventh circle (presumably meant to represent Uranus) and named it as 'Orque'. They gestured alternatingly to the seventh circle and their spacecraft, seeming to imply that they had come from Uranus.

Knowing how most of these alien encounter narratives tended to go, Higgins came to the (likely reasonable) conclusion that the entities may try and forcibly transport him to Uranus. As a subtle ploy, he showed them a picture of his wife and said that he either didn't want to leave her, or wished to take her on the seemingly-inevitable trip to Uranus. Falling for his subterfuge, the giants allowed her to leave the scene and he retreated into the forest beyond.

A considerably less accurate depiction

However, Higgins was not yet ready to completely leave the ostensibly-alien entities behind. His curiosity once again got the better of him and he decided to hide in some bushes and watch the humanoids for a bit. As if the situation couldn't get weirder, the entities appeared to be 'playing like children, jumping in the air and throwing enormous stones'. They played these games for roughly half an hour, and then boarded their craft once again after having 'carefully examined their surroundings'. The UFO took off with its signature whistling sound and the giants were never seen again. Except of course for when entities matching their bizarre description almost exactly were seen again in the Swedish town of Uddevalla in December of 1965 by one Richard Höglund!

'Sometimes I doubt that these things can happen. If it were not for the workers with me at the beginning, it might only have been a strange and fascinating dream' - Higgins later mused, presumably in response to questioning about the bizarre incident.

Monsters of Myth?

Legends from all across the world speak of giants constructing megalithic structures in the dark reaches of deep time. Some stories specifically refer to these massive creatures throwing giant stones between themselves to create these structures from those that they drop. Bigfoot encounters often feature the hairy entities throwing stones at alarmed witnesses, and poltergeists are famous for initiating physically-impossible showers of rocks from nowhere. It seems that the Others definitely enjoy rock-throwing for some reason or another...

Wrath of El Pombéro

Illustration of the character in question

Said Pombéro (no relation to Pom-Bears) is a rapacious dwarf-like creature originally attested to in Guaraní culture - but of which legends have since spread across Argentina, Paraguay and Southern Brazil. It is described as a diminutive humanoid with black skin and hairy extremities, and is usually said to be a harmless trickster figure - but is sometimes also known to kidnap women and force them into having sexual intercourse, and to commit other such heinous acts. Of course, this wildly unpredictable entity is naught more than local folklore, right? Well - according to a testimony given by one Liliana Nieves - this allegedly-mythical critter is all too real, and extremely violent...

Dark Forces in Barrio Santa Teresita
The community was already in a state of fear due to the recent appearance of a Aguara Guazú (maned wolf) in the area - which they had linked to the legendary werewolf-like monster known as the Lobizón. This general unease would reach a boiling point, however, when all hell broke lose in Barrio Santa Teresita...
Liliana's harrowing ordeal began on February 17, 2004 (the Tuesday before her story was told by the online news source El Norte Digital) when over 10 witnesses would concur that they saw a rain of stones fall onto Liliana's house - located 'at 31 and 0000 street in Santa Teresita'. Although everyone could see the stones falling, nobody except Liliana could hazard a guess at who was throwing them. The terrified homeowner claimed that she saw something tearing mandarin and tomato plants out of the ground in her back-yard, and then caught sight of a person running away from the scene. Her husband and another unnamed man chased after the entity, leaving Liliana alone in the house with her sister-in-law, Norma Cordoba.
While the two women were alone, a brick suddenly hurtled into the roof. Liliana frantically called Norma over to where she was standing, saying that she could see another entity. Norma said that she caught her first glimpse of the creature when 'a shadow shot out toward the back of the property'. The shadow in question continued to pelt the house with debris until 4am, at which point Norma had a breakdown and was taken to the hospital.
The rampant poltergeist-like activity briefly eased up, with nothing happening on Wednesday leading the beseiged family to perhaps dare to assume that Tuesday's events were naught more than a cruel prank. This hope, however, would be dashed when the assault resumed on Thursday - this time with even more ferocity. Norma was in bed at the time, and Liliana and her husband were sitting outside on the patio when stones started to fall onto the roof again. Norma got out of bed, presumably terrified that her ordeal was about to repeat itself, and went outside to see that her other neighbours were all aware of the commotion. The rocky rain struck Liliana's house and neighbouring properties alike, and at this point a decent portion of the community was stood outside in their back-yards gawking at the phenomenon.
All the houses in the neighbourhood are linked by a common patio, filled with trees with branches that touch the ground. It was into this forested area that Liliana strayed in an attempt to locate the source of the stone-throwing - this was evidently a bad idea, seeing as she didn't reemerge for quite a while. Frightened, her neighbours started to call out to her and received no reply until a local man ventured out into the forest to find the missing woman. He was successful in this operation, but what he found was almost certainly not what he was hoping for. Liliana was sprawled on the ground suffering from what appeared to be the aftermath of a savage blow to her face, severely wounding 'part of her eye and mouth' - leaving it 'all broken'.
When Norma was asked about how Liliana described her attacker, she claimed that her sister-in-law had said that it was a humanoid entity about waist-height on her - and that it had 'covered her mouth, dragged her to the bushes and beat her'. The creature apparently abandoned its hapless victim when it heard her neighbours calling for her, and was gone by the time they started searching for her.
When the community brought Liliana inside, she suddenly fell down onto the floor and begged her brother and neighbours to vanquish whatever it was that was grabbing onto her feet. Confused, the bystanders stood her back up only to watch her collapse back down onto the ground 'as if her feet were being pulled out from under her'. This frightening force was completely invisible to Liliana's would-be rescuers, but they rained down machete blows onto the space around her anyway in the hope that they would hit the imperceptible assailant. Liliana was completely hysterical, desperately pleading with the bystanders to save her from this phantom attacker. The police eventually arrived and took Liliana away to the psychiatric ward of the Hospital 4 de Junio, where she remained until February 21st of that year.
It was roughly midday on that Saturday - the 21st - when deacon Dionisio Castagna of the San José Parish visited the village, speaking to and praying with the frenzied locals. He agreed to bless their homes, and didn't question whether the story was true or not - simply saying that they should 'strengthen their faith in God and reaffirm family ties' in order to stay safe.
Mario Obregon, Liliana's brother, said that she would frequently say that the creature would appear and say that 'it wanted to take her away'. Trying his best to help, Mario would stand in front of his sister and try to defend her to the best of his ability, but could never even catch a glimpse of the assailant. Liliana said that the entity would continually appear despite her brother's attempts to protect her. A neighbour apparently came onto the scene with a crucifix and started to pray, but this seemingly only angered the creature - it would attack Liliana even more viciously and frequently. This episode was what frightened the locals the most, seeing as it was clear to them that there was seemingly an invisible force that was trying to push and drag Liliana. She said that it was a 'little man, all black' resembling an imp, and eventually the neighbours took her out of the house in an attempt to evade the entity, because it kept threatening to take her away into the forest and beat her.
According to a police report taken during the same period, a woman had been the victim of a brick attack on Friday (20th of February) at around 02:00am. Oddly, this is the same time as when the Aguara Guazú appeared in the neighbourhood. The police were dispatched the scene and apparently noted that there were brick shards on the ground near the site of the attack. An hour later, a deputy sheriff by the name of Aldo Fernandez led an operation to return to the site - and was alarmed to find that a large number of bystanders claimed to have seen the woman in question being 'lifted and thrown against the wall' by an invisible force, apparently resulting in her being severely bruised and needing to be hospitalised.

Chronology
Okay so as you can tell this is a very intriguing case, but the chronology of events seems to get a bit confused towards the end of the report. This is through no fault of my own, and this jumbled situation was present in the original source article. As far as I can tell, Liliana was attacked by the creature while out searching for the source of the stones, was brought inside where she was repeatedly pushed over by the entity - so much so that Mario stepped in to protect her but ultimately failed, leading to the community members taking Liliana outside to escape the threats of the creature. It was then that the police came. That's what I make of this, but I can see that other interpretations of the timeline might also be valid...
