As near as I can tell, Solana here was originally a brilliant scientist that, through circumstances beyond her control, inadvertently transformed herself into an anthropomorphized Apatosaurus. Thus acquiring a massive size, "big enough to fill the average living room" I hear, as well as a very well-rounded figure.
And even though she could probably crush me purely by accident, I refuse to take art-tips from a dinosaur; especially one that clearly doesn't understand the incredible genius and artistic vision that is me. X3
