There is/are (something)(somewhere)

It's common to use "there is ___" or "there are ___" when you're describing a scene or situation:

When you go in his office, there are books scattered all around.

You could also describe a scene this way:

When you go in his office, books are scattered all around.

But that's not as common, because it doesn't communicate the sense that you're giving a description. It sounds more like you're stating a fact. "Facts" are pieces of information like this:

Math textbooks cost a lot of money.

But a "description" has a slightly different feeling. It kind of invites the listener to imagine that they are in the situation you're describing:

There was a math textbook at the campus bookstore that cost a hundred and ninety dollars!

So when you're describing a scene, it's more common to use "There is", "There are", "There were", etc.:

There were books scattered all over.

some kind of (something)

The phrase "some kind of ___" can be used when you don't know exactly what you're talking about or you don't want to specify:

What's this? Some kind of stew?

I hear some kind of siren in the background.

a funky (smell)

A "funky" smell or odor is the smell of something that's a little bit rotten, moldy, sweaty, etc. You use it like this:

There's a funky smell in here.

There's something funky in that closet.

Other bad smells like the smell of chemicals are not usually called "funky".

"Funky" is a slang word, so you use it in casual situations.
