Fun fact: "spirit animal" is a term used by indigenous people, and it's important to them. So it's rather gucci for you to use "favourite animal" is you're a non-indigenous person! \(^_^ )/ #themoreweknow
Also btw, Octopuses have blue blood and they have a big clump of neurons in each arm, so when an octopus wants it arm to do something it tells it what it wants done and the neuron clump in its arm will figure out how to, and there are lots of other weird things about octopuses. I'm writing a story about one.
