As Sheldon listens to the sound of Shelly's stomach gurgling around him and the steady rhythm of her heartbeat, he suddenly hears the sounds of the throat above as she starts drinking. A moment later, cool water begins to pour down over him. The water keeps on pouring down, diluting the acids and soothing the soreness from having been boiled in that pot. Gradually, more and more water fills the stomach until he is completely submerged in it. Being a creature of the sea, he can breathe underwater, so he is in no danger of drowning. However, he knows that he is still in danger, as he is in a stomach and stomachs fill up with caustic acid and digest whatever is in then. Feeling rejuvenated by the water, he begins feeling around the top of the stomach for the opening to the throat. Shelly would feel this as a pleasant sensation almost like a sensual massage coming from within.
