My friend and his six roomies

Question

I got a letter the other day from my friend, who wanted me to meet his roommates. Here's how it read:

Hey pal!

When are you going to come by to meet my roommates? Here's a little bit about them:

#1 - You don't often see her outside the house, probably because she's always sleeping!
#2 - He can sometimes be blue, but he's a 10 in my book!
#3 - A well-rounded fellow, even though he kind of looks like a loser...
#4 - The fraternal twin brother of #2, though by looking at him, you'd think they were complete opposites.
#5 - I think she was a model back in the day. She's well-balanced and an excellent golfer!
#6 - She sounds a lot like her sister (#1) but is much more popular than her.

Please drop in anytime (as long as it's not too crowded). We could always use another like me around here. You know where we live, right?

Your friend,
[REDACTED]

The thing is, I don't know where they live, and I'm a little too shy to ask. However, I think if I figure out who they are, I might have a good idea of where I could find them. Can anyone help me out?

Answer 1

Building on Deusovi's answer, your friend and his roommates are all

Tetrominos. The roommates are the Z-, J-, O-, L-, T-, and S-blocks, which would make your friend the I-block. Everyone is happy when one of them is dropping in, as long as there is room for them.

So, you should visit them by

playing a few rounds of Tetris.

Answer 2

These are all

letters:

#1

Z: Z is a rare letter,and "zzz" represents sleep

#2

J: blue jays, and J is the tenth letter

#3

O: round, looks like a "zero"

#4

I or L? I and J used to be the same letter, and L is the mirror image of J (roughly)

#5

T: symmetric, tees are used in golf, and there was a car called the "Model T" (thanks, Will)

#6:

S is much more common than Z but it sounds nearly the same (apart from voicedness)

Answer 3

Look at the return address on the letter.
