Answer:
I know a word of letters three. Add two and fewer there will be. What is the word?
I am one small little piece of paper yet sometimes hold lots of value. I am all you need to get in to big events but will cost you. I am an important part of travel. And if lost you're not coming.
You can catch me but cannot throw me. What am I?
What color can you eat?
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.
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
