Raphie, does your tail have a mind of its own?
Sort of . It's... Complicated.
A Girafarig's nervous system is an incredibly complex thing. My tail indeed has its own brain... Technically. Think of it like a mini-brain. It isn't capable of independent thought or keeping secrets or doing anything I want it not to do. But that doesn't mean I actually have control over the little bugger. It's sort of like the tail has a little lump of brain in it just complex enough to house my id. It's the instinctive part of my mind. The aggressive part. The paranoid part. It's tied directly into my brain stem, my survival instinct and as such I share sensory information with it that could be used to identify threats.
It and my actual mind share a connection with each other through my central nervous system. Specifically it's directly connected to my brain stem through my spine, which is why I don't have much specific control over it. It's a survival mechanism. I literally can't make it ever stop paying attention for things that might be dangerous. It doesn't sleep or stop. It just watches. And tries to make me do whatever my instincts are telling me I should be doing. But because it only connects to my brain stem I don't have very good control over it. It's like my heart or lungs, it's viewed as just another organ with an automated function. I can't tell it to stop or start or how to do its job, it just does what it's supposed to do.
