Am I?

Am I an tiny little ant?
Crawling up a globe
Desiring the hidden
Stack of sugar cubes?

Am I a hippopotamus?
Smug wading in mud
Without any darn care
Impending extinction?

Am I that creepy spider
Building up a lovely net
Trapping whatever I can
For few morsels of food?

Am I a penguin at the pole?
Dressed elegantly partying
Even as the ice-caps melt
Dreaming a placid heaven?

Or am I a mere human?
Ever so lost and confused
Nothing will ever suffice
Desiring everything new
