Characters from "The Night" an animated story I'm working on where cartoon characters try to make friends with humans.
Generally non-human characters are referred to as "tunes".

You can find more stuff about it on my tumblr blogs but it's all conceptual snippets and out of order, so you'll have to dig a bit to understand anything.
