Fluttershy's got a bit of a secret interest: She loves letting herself sink in mud! Knowing full well she'd be mortified if anyone found out, she only sinks when she's absolutely certain no one will see her doing it, often late at night like this. She likes talking to herself once her mouth goes under as well, hearing how strange and funny her voice sounds through the bubbles she lets out. Don't worry, she can get back out no problem once she needs air!
