After annoying the giantess, she decides to swallow you to keep you quiet. You are not going down without a fight! She has some soda to hopefully get you to stop but ultimately decided to burp all the extra air out to lock you in. That seemed to keep you down. After being digested, you somehow manage to continue being bothersome, you gave her extreme gas. Only farting can bring a sense of relief, but the ultimate relief is letting you out. (Scene ends with me walking into the bathroom and closing the door)
