--That will be 20 coppers, 2 for each cockroach. And not just any, but the crazy ones, -- the vendor handed Feanor some specimens: large insects, about the size of a palm. They had long, serrated antennae, a dark red color, and a white face painted on their backs, each cockroach with its own unique face. In nature, they used these faces to scare away those who wanted to feast on the meaty insect. When Feanor took a closer look, he saw that these faces were gradually changing: yes, these so-called crazy cockroaches could magically change their color to ensure they wouldn't be eaten.
