In 2013, during the Lagos Urban Art Festival, ROA made his mark in the Algarve city with his urban art painting titled "Snails." The painting features two snails, which are a common presence in Lagos' environment, as well as a delicacy that locals love. ROA created a realistic representation of the snails, in black and white. ROA's detailed technique gives the snails a vivid and curious presence, as if they are looking at the world around them.
