WORD-SQUARES! WORD-SQUARES! WORD-SQUARES!

I'm Wally Wordsquare from Wordsquare Motors and I've ordered way too many wordsquares!

I've got to get them out of this lot and I'm passing the savings on to you!

EVERYTHING MUST GO!

For a limited time, you can get not 2, not 3, but 5 wordsquares for the price of one!

First, we have the WS1:

This first wordsquare will have you smiling!
It's a collector's item! Very uncommon!
It'll leave a rainbow in your eye!
It's so comfy, even baby birds can sleep in it!

Next, we have the WS2:

This one is fast like the wind! You'd think it was on cocaine!
This baby's got some history, a long backstory, there's even myths about it!
It's valuable, like mineral-rich rocks!

Imported from the Americas and their hemisphere!

We've got the WS3:

This one is even 50% off!
Imported direct from the Orient!
Such a good deal, you'd think I was fibbing!
Perfect for plowing fields or moving livestock!

Check out the WS4:

Now this one is quick, real speedy!
It's got one door that's slightly open, but that's no problem!
You should buy this one for God, or my brother Pete!
This wordsquare will beam you up through the stars!

Last but not least, the WS5:

I'm going to need some assistance with this one!
This wordsquare is downright wicked! I'm talking villainous!

A reminder, this is not pre-recorded! This is being broadcast, real-time!
I'm begging you, buy this one! Listen to my urgent requests!

Note: These are 5 unrelated wordsquares, each 4x4.
