Lapis is laughing so hard she's making snorting noises at Peridot and her dramatics. Actually, hang on, she might be wheezing, just a bit, leaning slightly forward and clutching her stomach.

She stops, long enough to open her mouth to say something.

And promptly starts laughing and snorting again. The thought of Peridot actually managing to pick her up is hilarious. She's too tall? Her arms and legs would drag on the ground!
