I kind of ran out of other forms of bonus content for Patreon, so how about uploads of Awful Hospital stuff at high-resolution along with never-before-shared background information?
Jerry's design is heavily inspired by the aesthetic style of artist Mark Powell's gruesome, meaty nightmare dioramas, which were also the basis for SCP-610, or "The Flesh That Hates."
610 obviously has a lot more in common with the Parliament of Old Flesh, but it wasn't the main inspiration. There have been many other instances of creeping, spreading, monstrous biomass in popular fiction, especially video games including Starcraft, Halo, Dead Space, Warframe, Terraria and many others.
What I've never personally seen, however, was this type of Evil Flesh Moss given any relatable personality or imagined into characters with any streak of humor to them.
Jerry is the kind of "person" who might live in an all-consuming biomass the way some bored working class schlub lives in a sprawling city. He's a cog in a machine, and he doesn't really care either way except to complain about it.
