Atop the shelf, Ylva briefly turns back into herself (clutching her perch carefully in case of unexpected wobbling). Fortunately, she isn't going to be that size for long. She raises a finger to César, giving him a saucy grin, and then changes shape.

She is a cute little snake, with batlike wings. Ylva spreads her wings to show herself off, and launches herself into the air and flaps to the top of another shelf.
