DESCRIPTION
One way that Robin earned a living in her rootless years was to set up glory hole stalls, all manned by cloned parts of herself to maximize profit... and pleasure. Sailing with the Strawhats, she has less chances to indulge in this, but whenever they stay for a longer time in one port, she takes the chance - but nowadays for free.
The other women in the (Spidu extended) crew also join in sometimes.
