Pen is considered one of the "cool" characters and is good friends with Eraser, Blocky, and Snowball. However, unlike them, Pen is more optimistic and sensible, and has his nicer moments more often than them; an example is when Firey allows Pen and his three friends into Dream Island, Pen is the only one who thanks him. A more subtle example is whenever the eliminated contestants voted for anyone but Leafy to win Dream Island, Pen is the only one out of his friends who didn't slap them for it.
