I'm not sure what a wiffen is, but it sounds like something I'd want to avoid. Maybe it's a creature with sharp teeth and a bad attitude, or a disease that makes your skin turn green and your hair fall out. Whatever it is, I'm sure it's not good.
I've heard that wiffens like to hide in dark places, so be careful if you're ever exploring a cave or an abandoned building. They also like to eat small children, so if you have any kids, keep them close.
If you ever do encounter a wiffen, don't panic. Just run away as fast as you can. And whatever you do, don't let it bite you. I hear their bites are fatal.
So, there you have it. Everything you need to know about wiffens. Just remember, if you ever see one, run away as fast as you can.
Just kidding. There's no such thing as wiffens. I made it all up.
But seriously, if you're ever feeling scared or anxious, just remember that there's no such thing as monsters. They're just figments of our imagination.
So go out there and enjoy your life. And don't worry about wiffens.
