Clarence: Clarence is the first animatronic made by RR INCORPORATED, It's pretty heavy and just took 4 days to make! This animatronic had some unused features, the only one that was used was "regnad_robotics.ppx". This filename is most likely a feature that was used in previous companies.

Jeff: Jeff is the lightest animatronic here, he was made to teach children about the human body and other things. Jeff was about to be scrapped but got saved by the designer of the animatronics (The guy who basically built the animatronics)

Sumo: Sumo was made out of scrap metal, crumpled fabric and a strange robot found in an alleyway, origins unknown, one of the co-workers recorded a tape regarding this animatronic, but it was discarded due to this being unnecessary.
