In India, there are many grannies' tales that describe a bunch of people around the King who always say, 'yes, your highness, yes'. No matter how worst that idea or opinion of the King is. Let's build a context.
The King is planning to dig a well on a mountain!
I'm planning to dig a well on a mountain nearby our palace. So, whenever I'm up there for my leisure time, I can have water whenever I want. What do you say?
A bunch of [this is the word I'm searching for] replies:
Oh, yes, why not?
Now it's pathetic and foolishness to have a well there. But since they are ____________, they'll say 'yes' to whatever the king says.
A very important note: I know the word 'flatterer'. This is not what I'm looking for. Because these guys don't praise. They just say, 'yes, yes' to anything that the King says.
A typical flatterer will keep on praising the King.
Oh King, what a nice sword you have (though it's rotten!)!
Again, I'm finding a word for those who don't praise/say nice things, they just 'AGREE' whatever their bosses or kings say.
To my mind comes another word: 'flunkey'; but do natives use this that way?
