Bloco da Lama mud party, Paraty, Brazil 2017 photos: The filthiest part of Carnival

Take at look at this year's traditional "Bloco da Lama" or "Mud Street" carnival party, in Paraty, Brazil in the gallery above.

Legend has it the "bloco" was born in 1986 after local teens hiking in a nearby mangrove forest smeared themselves with mud to discourage mosquitoes and then wandered through Paraty.

The party grew year after year, but revellers eventually were banned from parading in the colonial downtown after shopkeepers complained pristine white walls were stained with the hard-to-remove mud.
