I'm big and powerful, but I like to sleep. I pay no mind to counting sheep. I protect my pride with style and grace, though sometimes I choose my own pace. King I am, and I'll stand my ground; should I leap, there's no sound. I've a mane of gold and eyes like the sun- most of my kind think boxes are fun. So, if you see me someplace near, please don't worry, and have no fear. I'll be resting in the shade, waiting for the day to fade. Just know that when twilight's here, I can see you crystal clear. This is when you must take care, for when I'm hungry, all beware.
What am I?
I gave you a clue!
