Hi guys. I watched the movie back in January and absolutely loved it. For my bday my mom got me the blood movie poster (just arrived today!), and she asked me what the slug thing was on it. Me not really remembering such a slug went to look at the poster on the website (she meant the eel sticker). Explained that it was the monster and continued exploring the site. I managed to find a symbol I don’t recognize on the “play iron lung” tab. I proceeded to click on it and it took me to an another tab that showed a picture of what looks to be the bottom of the blood sea. There was also text that flashed but I wasn’t able to make it out. Any thoughts on what the symbol is and what this could mean?
