The Origins of Nyan cat...?

So I'm writing this at like 4 am so bare with me XD BUT my mind was just thinking how was Nyan cat even created... ALSO the song??? how does that even happen. A cat that poops rainbows and the body is a POPTART! Honestly, I'm so shocked how someones brain would make this masterpiece... I'm rambling at this point but I'm just so stunned!! Also what's the backstory of Nyan Cat??? Does it have siblings!! Is Nyan cat a LGBTQ icon?? Is Nyan cat truly Nyan cat or just a cat? so many questions and none answered... sigh... OMG WHAT IF NYAN CAT IS THE REASON WHY SKITTLES EXIST... guys I'm a genius...
