Answer:
What can fill a room but takes up no space?
I'm tall I'm round and hollow Seems to get chewed a bit But you'll rarely see me unless the other end is lit.
I go inside boots and outside shoes. What am I?
I can wake you up in the morning but I require no electricity or winding.
I contain five little items of an everyday sort. You can find all five in a tennis court.
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
