Vegapunk says his brain has grown into the world's largest brain and continues to grow. Chopper is amazed: "That was incredible! As a researcher, are you strong too, Dr. Vegapunk?" Vegapunk answers, "Of course!!" Luffy asks whether cutting off his head made him an idiot, but Vegapunk snaps, "Don't underestimate my genius, you damn brat!" He explains that the apple on his head is an antenna. The top of Egghead, behind the giant egg, has "Punk Records" written on it, and Vegapunk says that is a hangar for his brain. Even if he is apart from it, the antenna connects data via psychic waves, so there is no problem.
