Carlson Fiddle was a manufacturer of mechanical puppets hired by Andrew Ryan to build the Rapture theme park, Ryan Amusements. Carlson initially wanted to create a park that would simply please the children of the city, however, Ryan insisted that it be educational. During construction, Carlson gave some consultants of Ryan a backstage tour. Among them were several notables, like Sander Cohen and Sofia Lamb. The result of this planning was the Journey to the Surface ride, which was designed to scare children away from ever wanting to go to the surface.
