You have to pick:

If you cut them off they grow back

Everyone talks like an evil gnome and all sounds sound like they went through a creepy, evil echo filter

they are flesh-eating so would they try to eat you?

What do you mean creepy?
does everything you hear sound like terrifyingly creepy?
or is it just some things in particular?

Everything.

Yes, but you control your fingers. So they can't pull your hand toward you, but if you leave your hand resting on your chest... bad things happen. :(

If everything sounded creepy, you'd get used to it, and it would no longer sound creepy.
