Like the Western Chili, the Swallowtail larva was like Gu Tian Le and Huang Bo, like Leonardo De Caprio and Nicholas Cage's rotten movies. These were things that some found rather disgusting and ugly. Letting it touch one's body was gross. Merely looking at it could make one's eyes water.
This bug may be more suitable to grow in the depths of the ocean. If no one could see it, it could grow in any way it wanted.
The Western Chili was covered in defensive burrs which were thick and hard. Its bottom was covered in thin and dense burrs. The most concise description of it was a moving prickly pear.
The fat boy should've been thankful. When the bug had fallen on him, it was probably the thin and dense burr that had hit him. If it had been the thick and hard burr, he would probably be in such pain that he would be rolling on the ground.
