Okay, so I made a Tumblr Post with cited sources: Here
Basically. C is just AB but specifically for Cats? It's a super rare blood group. And Mike is there too. Mik is the name of the new cat blood type classifications, after the first Cat discovered with the rare blood type, Mike.
And D means you have the Protein. It's +.
Negative means you don't. All the Blood Types are negative protein, except D.
Someone please tell me I'm not just losing it. And if I am, confirm that for me so I can rest. Also, let me know if I'm doing this wrong, never discussed on a Wiki in my life.
I think you're most likely losing it (us Deltarune fans tend to go very insane inbetween chapters) but you could be onto something
u remind me of this one guy @DaPixl2000 hates the one thats like
"blue.. green rose"
"chapter 5 you meet the grek"
or just random stuff up
Did you know they discovered negative light photons??
Did you know there's "dark protien" or whatever it's called??
DID YOU KNOW THERE'S A TOWN IN REAL LIFE THAT NEARLY CORRESPONDS TO HOMETOWN'S GEOGRAPHY?!
No, I actually see where this guy is coming from. A bit of it is stronk inducing rambling, but this theory is at least grounded in something.
I do apologize for the formatting and writing style of this post, but in my defense, it was 2 am.
