Answer:
I describe a toilet cleaner as well as one of Santa's reindeer
I fly yet I have no wings. I cry yet I have no eyes. Darkness follows me. Lower light I never see.
I have no bed to sleep and no palace to live. I don't have a single coin but I am known as king. What am I?
I go in hard come out soft. Blow me hard and I’ll make a pop.
I open to close but I close to open. I'm surrounded by water but I'm never soaking. What am I?
Some try to hide some try to cheat. But time will show we always will meet. Try as you might to guess my name. I promise you'll know when you I do claim.
