A mysterious human being who studies at the UCSB Department of Physics. This creature seems to feed on the knowledge of high-energy physics, machine learning, plasma science, and history. It became especially appetite when he smelled a detector or a physics dessert beyond the standard model. You may use Ramen, Board games, or a Calorimeter to decoy this creature. To dispel this creature, you may use bugs (C++ bugs are the most effective). Witnesses described it as a friendly creature with an ardent heart and a sheer will. Most of the witnesses became good friends with it. Don't be scared by its outpouring of enthusiasm, it might just want to say hi. However, be careful, most witnesses recount that their belly hurts when interacting with Billy because they laughed too hard when he talked about his stories.
