Answer:
I am a desire to munch
I ask no questions but receive a lot of answers. What am I?
I come without being fetched at night hides away as soon as daylight strikes. Although I may look small I am much mightier than what you can imagine.
I fly to any foreign parts assisted by my spreading wings. My body holds an hundred hearts Nay I will tell you stranger things when I am not in haste I ride and then I mend my pace anon.
I am used when you jump off a bridge for fun.
What is lighter than what it is made of?
