Answer:
How many letters are there in the English alphabet?
I'm an animal. I love marching. I always wear a tuxedo. What am I?
I am a shower that lights up the sky
In the sun I like to play; in the rain I goes away; walk or run I always follow; in the mud I always wallow.
I ask no questions but receive a lot of answers
No matter how little or how much you use me, you change me every month.
