Aw fine...

There's two of us-2 things
we rule the land-King and queen, well they rule the land :\
we sound the same-save the king and save the queen, sounds the same right?
but we don't blend-save the KING and save the QUEEN, see sound almost the same, but don't blend

So the answe is.... Save the King and Save the Queen
Why couldn't you have just kept guessing
