You have to pick:

Boingy! Boingy! The wonderful thing about tiggers, is tiggers is wonderful things!

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

Best superpower ever.

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

Everything.

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