That's either a volcanic eruption or a massive forest fire and a very attractive cat(?) girl. It's hot in both senses of the word.

I'm guessing, from the fire & the blue sphere she's sitting on, that this is an anthropomorphized version of the Firefox logo. But I could be wrong.

Short haired Horo is my first thoguht

Looks like a rock to me.

From the thumbnail, I thought it was a catgirl washing herself in the traditional cat style.
