Artista: Relient K
  Canción: I'm Lion-O

Chillin' at the lair.
Snarf, me and the twins.
My favorite feline is the one who wore cheetah skins.
Fighting evil, we drink milk, and we purr a lot.
Ask em to cross them, and I would say I'd rather not.
Thundercats Ho!
I'm Lion-O!
Sword of Omens, come to me.
Your eye opens so you can see.
Fly from the sheath into my paw.
I am the greatest Thundercat of them all...
I'm Lion-O!
