Answer:
I work when I play and play when I work. What am I?
I roam through the lands hoping to rescue my love. I search high and low and will stomp on you if you get in my way!
When young I am sweet in the sun. When middle-aged I make you gay. When old I am valued more than ever.
I am not very commonly found! Only in some rainforest! I have an odd number of toes! I'm very lazy and hang upside down!
I am essential to life on earth! I am split into thirds. Two thirds are the same. One of the thirds is 8. The other two are 1 each.
Almost everyone needs it, asks for it, gives it. But almost nobody takes it.
