In "Bridge Crossing", when Eraser says he doesn't feel using the ropes to cross the bridge, Pen tells him he wants to win to get Dream Island, stating that if he did, he would name it with a big sign that reads "Pen Island" except with no spaces and all caps. He then tells Eraser that they go ahead and try to win it.
In "Oneirophobe's Nightmare", Pen, was skipping at Pen Island. Behind a bush was Are You Okay. Eraser thought that this was supposed to be Pen's nightmare but instead it looks like a dream to the former.
