Oh, you mean the moisture inside in the pepper itself! Yeah, different vegetables have different water contents. It means how much water they keep inside of them. Some things have more water in them than others.

Don't eat it raw. I know you're a hollow, but for all we know your digestive system will work differently here than you're used to. Raw meat can contain things that make you sick, which is why you cook it. The heat can kill those things so they aren't a danger anymore. These are called bacteria. They're so small you can't see them without specific tools, and they can make you throw up or shit a lot.
