Another challenging packing puzzle from the devious mind of Alexander Magyarics. The design is reminiscent of a cartoon mouse hole cut through the molding at the bottom of a wall. The top piece slides back and forth, and the goal is to fit the three purpleheart pieces (which kind of look like little mice) into the box. Be warned; even experienced puzzlers may feel as frustrated as Tom chasing Jerry.
