I think if there is canonically going to be a zombie invasion in October I want you to make a zombified eggyhead that would be a rotten egg (It wouldn't matter if you put a bite mark or anything since the zombie virus is airborne, and eggyhead clearly has no way to protect himself from that)
well the reason inkmatas can't catch the virus through the air is because viruses thrive in the cold, and last time I checked Inkstone is extremely hot
Inkstone makes the Immune system of the user way better then normal. This immune system can fight off infections such as Cancer, HIV, Measles, the flu, and Coronavirus better then most immune systems
