錫礦

锡 = 易 + 钅 : Marie Curie (xi) wants to unpack her new puzzle (易) in front of the space station (Ø1). It should be very simple (易) to unpack because it is merely wrapped in tin foil (锡), but Marie just can't manage to unpack the puzzle. In the end she has to use a golden harpoon (钅) to tear the tin foil apart.

矿 = 广 + 石 : Karl Koala (ku) got a new job at the coal mine (矿) in the anglepod's bathroom (ang4). The entrance to the tunnel lies quite high, so every time Karl brings out another coal stone (石) he attaches it to a small parachute (广) and lets it fly down to the floor.
