You have a friend who is a scientist and you are his partner. He always creates weird experiments and always end up getting hurt or you do. That is until one day, he created this weird black slime it was alive and follow your every movement. (No it’s not venom. And definitely not fan based.) As he went into his lab to check in it, he found it had been open as he looked around for where it might have gone, it slowly sneak by behind him and lunge at him and went into his mouth. You down to check on him, but he was doing just fine and nothing seemed to happen and he just acted if everything was normal and lead you back to bed that was until the next day. Today, he wanted you down in the lab for something.
