When liquid splashes me, none seeps through.
When I am moved a lot, liquid I spew.
When I am hit, color I change.
And color, I come in quite a range.
What I cover is very complex, and I am very easy to flex.
What am I?
I usually go with a special beef, I'm a green vegetable, like a leaf. I'm a yummy addition to your St. Patrick's Day dinner. If you eat me a lot, you might even get slimmer. What am I?
