On June 20, Luciana Castello Branco Rangel of Brasilia, Brazil, looked out the window of her home right after her dog awoke in the middle of the night and raced to the balcony. She was curious about what attracted her dog's attention and was startled by what she found. Outside her window was a busy scene, a parade of at least 10 capybaras marching down her street in a single-file line. Castello Branco Rangel filmed the shocking sight and posted the clip to her TikTok, and it has received over 18 million views.
