I make up most of the air you breathe, Yet alone I’m hard to keep. Plants need me to grow up strong, In lightning storms, I dance along.

I rule a golden kingdom, though I wear no crown, Where grass grows tall and the hot sun beats down. A pride is my family, though we never boast, We stalk through the shadows where prey fears us most. With a roar like thunder and a heavy mane, I am the fierce monarch of the African plain.

A mythical monster and an insect join to form another insect

I have no rivers, Yet waves still appear. The sun rules my days What place am I here?
