The disease squirter.
Heya, just another noob here with an idea.
I have an idea based on this SCPfuel image for an SCP that, when approached by a higher mammal, usually a human being, will "squirt" a highly infectious liquid out of one of its many pores. Any person whose bare skin comes into contact with the liquid develops a random infectious disease. Sometimes it is only a simple cold, other times it is a deadly disease, and sometimes it is even an SCP such as SCP-008, SCP-081, or SCP-217.
