Moonrise gulps yet again, gradually pulling her in up to her neck. He is a little concerned about the sizzling sound at first, but since he doesn't feel any pain, and Lyra doesn't seem to be getting hurt either, he pays it no mind. He soon slurps her head into his maw, chuckling a little as he runs his warm, slimy tongue across her face and beak. With one final gulp, his throat sucks in her head and closes behind it, slowly letting her slip down into his belly. There is plenty of space inside for her to move around, since the majority of his body is taken up by his stomach. The walls faintly glow, allowing her plenty of light to look around. If she looks closely enough, she will see that it's not his flesh which is glowing, but the saliva coating the walls.
