What is this green slime guy in the shop, and what does he do?

Here's a screenshot of him: http://prntscr.com/ap1d13
I found him in Chamber 1 if that helps.

You can drop stuff to him and he gives you cash.

Check keybindings. Hold F I believe?

you can drop your passive items by holding tab (looking at map)

You can drop your gun by holding F
You can drop your active item by holding G

You can sell junk too!

how do you pick which one for the passives though? didn't think you were allowed to sell them.

Wait what? You can actually drop him stuff for money?

On PS4, at least, you open the map, use the D-pad to select a passive then press the switch weapon button to drop it.

This really helps getting the prime primer, thanks

In the Hollow, if you give him a master round and at least 2 items or guns in his room, his grid will blow and you'll have access to a secret floor

[ExaltedDuck]

If you play on a controller, dropping is by holding up on the d-pad or down on the d-pad. One direction is guns, the other is active items. I always forget which is which and just test it away from the grate right before using the grate.

For passives, from the map screen, you can move a cursor over the item you want to drop and press the top face button ("Y" on an x-box style controller, which is normally the weapon quick-swap button during gameplay). I don't know the keyboard mapping for it but you could probably find it in the button mapping options screen.

Why nobody tell that he have a secret floor if you do something in floor 4?

If you sell him some weapons and one mastery that you win killing one boos with no hit he go and open a way to his "world" where you can fight him as a final boss.

The weapons or items you have to sell to him are not always the same because each weapon and item have a "price" and you cant see when is enough.

I recomend to sell first the boss mastery bullet and then start to sell him weapons or items until he leaves and open the "door".
