What are the ones that you are having difficult with?
It's only a handful (based on the total EB members' population before 26th Aug).
Take a search for the closest LEGO set there is to a Spartan action figure. [There is a keyword inside the clue itself. You got to find out which one it is.]
It's a witch! As we all know, the best way to deal with witches is to hunt them and put them on trial for their crimes. This noble witch is suitably found paying for its crimes in such a place. [There are not a lot of topics in Eurobricks where there are witches involved. I am sure you have seen the topic before but you are not observant enough to note its location.]
Hope these clues can help you.
As long it's subtle and not obvious and at the same time, involving some thinking, it's alright to offer some suggestions.
