"I'm Lion-O ('All Work And No Play' Version)"

We want chicken, we want liver,
Meow mix, Meow mix, please deliver.
Meow-meow-meow, you can purr along too
'cause I'm not just a cat,
I'm more than that...
I'm a thundercat, too.

Chillin' at the lair,
the cats Snarf and the Twins,
my favorite feline is the
one who wore leopard skins.
Fighting evil, they drink milk
and they purr a lot.
Ask me to cross them, and
I would say I'd rather not!
I'd rather not!
I'd rather not!
I'd rather not!

So, hey guess what, oh whoa...
So, hey guess what, oh whoa...
I'm Lion-O!
So, hey guess what, oh whoa...
So, hey guess what, oh whoa...
I'm Lion-O, I'm Lion-O!
I'm Lion-O, I'm Lion-O!

Sword of Omens, come to me.
Your eye open, so you can see
Fly from the sheath in to my paw.
I am the greatest Thundercat of them all!
I'm Lion-O, I'm Lion-O!
I'm Lion-O, I'm Lion-O!
I'm Lion-O, I'm Lion-O!
I'm Lion-O, I'm Lion-O!
