So now I have an itchy spot where the stupid acariens got injected, and a sore throat (typical the day after I get my shot). I imagine an exoskeleton would make it hard for them to give me the next injection. That sounds good! But the other presumed powers (the ability to make others sneeze and feel drowsy) don't sound all that great. Too bad I'm not getting feline injections (but I'm not allergic to them, thankfully).
Perhaps after I finish Marc's avatar, I'll update my own to show what I might look like after receiving injections of radioactive feline serum.
