I've actually really grown to like Cozy ^^  And voicing her is just as fun!  Obviously she is based on Darla Dimple so I changed the lyrics a bit to fit her more!  Also the Tarturus part was a bit random lol.
I was trying to find a line that would work and realized Tarturus is in a sort of different dimension from Equestria so I guess it works? Hope it's okie!

I only own my voice

Lyrics:
[Cozy]
I've seen em come
And I've seen em go
There's one thing that I know

You gotta give the ponies
PUNISHMENT :)
Or you'll wind up back in Tarturus, Equestria

[Chrysalis]
It's actually outside of Equestria

[Cozy]
Whatever
They like it big!
They like it loud!
Maybe a little bit jazzy sometimes...
Mr. Grogar listen to me
You don't have to be good
But you had better be...

BIG AND LOUD!!
Big and Loud!!
Gonna make your villians proud!
Make it Big!
And...
LOUD!!
