EXPLANATION:
Ah, this riddle is talking about something that’s always around, but you can’t see it unless you look really closely. It’s dust! People are hired to get rid of it because it can make things messy and dirty. It likes to hide under your bed and in other sneaky places. No matter how many times you clean, it always comes back. And if you try to bite it (which you shouldn’t do), it can make you sick because it might have yucky stuff in it. So, the answer to the riddle is dust!
Well, that’s all for today. See you on the next riddle!
