Pin appears to be a standard plastic pushpin, with a red body and a gray point. She has a distinct accent of pronouncing words separately.

In BFB, she shows concern for the well-being of her team and wants everyone on "The Losers!" to be independent. She also motivates her team, frequently encouraging them to be strong in times of difficulty. Pin and Coiny were a great couple, they loved each other, but Coiny became desparate and stopped loving Pin, and cheated on her. They broke up.
