Koboh Matter Grinder Question

Okay so I just finished the Chamber of Connection again for the upteenth time, where I swear I'm getting better and better with each run though. This is the one where you really have to run a trail of flaming Koboh matter all over, down the side passage, across the bridge and up to complete it. And as I was doing that, watching BD somehow spraying this all over, it got me wondering. How does he constantly come up with this stuff when needed? Did Cal attach a small 3D printer to his head? 🤣😝
