he ate something way too spicy and it made him begin to bloat

I came up with something, but it turned into a wall of text, so reply if you're okay with me posting it in a comment, or note me if you want me to send it to you in a note.

go ahead. :3

Research Journal, Day 15. After studying the new type of shellfish I discovered in every way I could think of, I decided it was time for the only test remaining: how does it taste? In short, the flavor and texture are typical of shellfish, and rather good. However, the shellfish apparently has some kind of defense mechanism that, ironically, triggers only if it is digested--in other words, not so much for an individual's survival as to discourage predators from consuming more of its kind. In fact, given the relative size of predatory organisms in the area, I would go as far as to surmise that the shellfish's posthumous defense weeds out any predators inclined to consume it. I inflated to twice my ordinary girth in fifteen minutes, and swelling continued for an hour in total. It stopped about an hour ago, but my torso and limbs are all completely spherical and more than four times their normal diameter. Additionally, attempts to expel the gas I'm inflated with has revealed that it does not actually build up in the digestive tract, but instead saturates the surrounding tissues. I am in no pain, but my limbs are so tightly swollen that I can barely move. If my pencil and notebook hadn't been so close to hand, I might never have been able to record these events. As it is, with no apparent sign of deflating any time soon, I may be stranded here. At least the gas seems to be discouraging my body from feeling hungry. I wonder how long that will last.
