I finally made a little sheet for scud body mods and decoration too!

Anything scuds decorate themselves with is either removable, or it just comes off when they molt out of their current carapace. Adults only molt every 2-3 earth years, so tattoos and engravings stick around pretty long but not forever. The “limpets” I drew here are one of many intertidal critters scuds will put on themselves as decoration, but are by far the easiest to care for. Off-duty “limpets” are kept in a small terrarium and fed table scraps. Scuds can rent them from living decoration shops instead, if they don’t want to care for their own dec-snails. Adult scuds also have some issues with unwanted decoration, ie, small marine “invertebrates” and “plants” rooting on their body in between molts. Scraping off sessile hitchhikers is an important part of scud hygiene.
