“I wonder what will happen if I put THIS together with THAT…”
The brilliant Scientist’s specialty is finding new and interesting ways to combine things together. She’ll spend all night in her lab analyzing how to connect bricks of different sizes and shapes (she won the coveted Nobrick Prize for her discovery of the theoretical System/DUPLO® Interface!), or how to mix two colors in one element.
Thanks to the Scientist’s tireless research, Minifigures that have misplaced their legs can now attach new pieces to let them swim like fish, slither like snakes, and stomp around like robots. Her studies of a certain outer dimension have even perfected a method for swapping body parts at will!
