Capybaras keep their chill while crashing Brazilian legislatureBrazil’s beloved capybaras, the world’s largest rodents and social media favorites, made an unexpected appearance inside the legislative assembly building in Brazil’s central-western state of Mato Grosso. CUIABA, Brazil (AP) — One Brazilian state legislature has increasingly found its voting sessions invaded by a group of unexpected visitors: capybaras. The notoriously chill rodents strolled through the front door of the local legislative building in Cuiaba, in the central Brazilian state of Mato Grosso, and surprised lawmakers who were preparing for a vote last week. Capybaras have surged in global popularity online due to their remarkably calm demeanor and highly social nature. Their visit caused no damage to the Mato Grosso state legislature.
