Tsunami wasn't really a fan of this whole 'desert' thing to start with. Comes with being a SeaWing. The lack of water and the heat weren't critical yet, but it was enough to make the already snappy dragon a little snappier than normal. Hunched on top of one of the rapidly moving train cars, she has her long tail tucked around herself to make sure that it doesn't get caught on some passing terrain or the train itself. Why did scavengers (no, here they call themselves humans apparently) build everything so tiny--she was never going to get inside without drastic measure. Glumly, she reaches out to prod a talon against one of the vents--big enough for a human to get through and maybe her head and neck but no way was she getting inside unless they ripped the roof off.

Hey. That's an idea. She reaches down to where the roof meets the wall of the train car and begins poking at it experimentally, just to see if she can get a talon through. Someone might want to say something--but then again, she is a dragon...
