樸實

朴 = 卜 + 木 : Petra Penguin (pu) celebrates a very plain and simple (朴) Christmas in the space station (Ø3). She has a simple Christmas tree (木) and to let it snow she simply (朴) beats the Christmas tree with a voodoo staff (卜) so that its needles will come off and float all around.

实 = 头 + 宀 : Sherlock Holmes welcomes professor Skull just inside the entrance of the space station. Professor Skull has not a complete head but only a skull, and a solid understanding of solid state physics. She really is an honest person and still wears her graduation cap.
