Steampunk Wall Tentacle by ArtAkimbo on Etsy. "Cthulhu wall tentacle that’s big enough to mess with a room. This is a 24″ octopus arm cast in urethane. polished and painted, protruding from a 9″ round rust encrusted porthole, with a slosh of rigid seawater. Extends from the wall 18 1/2″. I cast these from my own molds made from my original sculpt. No animals were harmed in the process, save the usual cuts and scrapes to my poor, gnarled fingers."
