**First Appearance:** #book11 #### *AKA Mood Crabs, The Between* An endangered species from an undeveloped planet, being removed, killed, and a very small part of their carapaces used as an ingredient in a beauty product. Showing early signs of sentience. They use tools, for instance, and construct dwellings. According to the biological background on them, they also have some cryptic form of communication—it doesn’t involve anything physical, like sound, visible light, or airborne chemicals, at least that anyone can discern. They may have some latent psychic ability.
