In this jungle-soaked mystery, Brain Bamboozle dives into a real discovery of an ancient Amazonian city, a new species of glowing poison frog—and the eerie reports of a ghostly dog said to guard the ruins. Is it cryptozoology, chemistry, or collective madness? Buckle up.

....

The claim that explorers stumbled upon an ancient lost city deep in the Amazon is true. Recent scientific discoveries have revealed huge ancient cities hidden under the Amazon rainforest, such as the one found in the Upano area of eastern Ecuador. These cities show evidence of complex urban societies with houses, plazas, roads, and canals, challenging previous assumptions that the Amazon was only inhabited by small nomadic groups or tiny settlements[1][7].
Regarding the glowing poison frog, it is also true that some Amazonian frogs exhibit unusual coloration and even fluorescence. For example, the world's first fluorescent frog was discovered in the Amazon, glowing green under UV light. Additionally, a new species of bright blue poison dart frog with copper-colored legs was recently identified, highlighting the remarkable diversity and striking appearance of Amazonian amphibians[3][4][8].
As for "something watching them... something that shouldn't exist," this likely refers to local legends and folklore rather than verified scientific evidence. The Amazon is home to mythical creatures such as the Mapinguari, described as a large, hairy humanoid with a cyclops eye, which has been reported in folklore and some anecdotal sightings. However, zoologists generally consider these stories to be cases of mistaken identity, possibly involving known animals like spectacled bears. There is no scientific proof of any supernatural or unknown creatures lurking in the Amazon[5][6][9].
In summary:
- Ancient lost cities in the Amazon have been scientifically confirmed[1][7].
- Poison frogs with striking colors and fluorescence exist in the Amazon[3][4][8].
- Reports of mysterious creatures watching explorers are based on folklore and unverified sightings, not scientific fact[5][6][9].
Thus, while the discoveries of lost cities and glowing frogs are real, the idea of something supernatural watching explorers remains a myth.
