The doctor laughed inside as he turned and let the rock bounce of the protective sheath on his back tank. In response, he produced a canister from his belt, and began to audibly laugh. He screwed the canister to the side of the spray, and started his assault. He spin around, and pulled both triggers, one igniting a small butane torch, and the other sprayed out the contents in the canister in a tight stream. The mixture of Octane, Benzine, and Polystyrene, known to the humans as Napalm, ignited, which, if it connected to the target, would cover him in the sticky burning substance.
