Infection au

So i made this irl so basically there's this infection that someone made because they thought it would be fun to make and people got really sick and infected stages. stage 1: aggressive stage 2: face changes and behavior changes becoming more aggressive stage 3: more likely to attack and has black goo with sharp teeth stage 4: neck detaches with a long stringy black goo dripping stage 5: if you got this far then you turn into a flower that leaks the infection.
