At my front we have one of the strongest bugs that live in a hill, just without the tea I hope. At the end we have what you will be if you're bitten by a supernatural lycanthrope. The coolest letter you doodled in school is in the middle. Assembled well and you will solve this riddle.

I can be clean. I can be dirty. You may want to use me at your own risk. However, if you brave the nasty, you will be relieved at the end. What am I?

I have a long arm but no muscles, and I can throw things further than any athlete. I was born in ancient times to knock down walls, yet I never use a hammer. I’m not a plane, but I can make things fly; I’m not a feline, but my name starts with a cat. What am I?

I'm screwed to the wall to hold up a shelf. After all, I can't hold the books all by myself.

Four wheels, wood I boast, Concrete waves my metal friend, Balance, then I roll.
