The treasures are in the mouth where there’s ice. How cryptic! You want to find the treasure, that’s for sure (treasure is great!). It is somewhere where there is ice, so maybe the arctic? What you are looking at is a diagram which will guide you there.
What will you do when you find these treasures that are shown on the diagram? Well, you get there, and you find that the treasure is actually a wooly mammoth! What will you do with this wooly mammoth? You grab it and put it in your zoo (ず).
