A herd of capybaras entered the legislative assembly building in the central-western Brazilian state of Mato Grosso. This was reported by Qazaqyia.kz citing Associated Press.

The world's largest rodents and social media favorites calmly roamed the halls of the legislative building in Cuiaba, surprising lawmakers who were preparing for a vote last week. The building sits next to a park filled with wildlife.

Staffer Nayara Bueno filmed the unexpected visit of the rodents native to South America on July 30 and tried to lead them back to the park.

"They show up here quite often, so we've gotten used to seeing them," Bueno said.

Capybaras have surged in global popularity online due to their remarkably calm demeanor and highly social nature. As semi-aquatic animals, they thrive near rivers, lakes and wetlands, often living in groups and growing to weigh up to 80 kilograms (175 pounds).

Their visit caused no damage to the Mato Grosso state legislature.
