Pull a rabbit out of the box! Is the rabbit looking through the round hole or through the star-shaped one? Is it standing on top of the yellow, the red or the blue block? Some challenges may look very similar, yet the solution can be completely different depending on how far the ears of the rabbit stick out. Bunny Peek-A-Boo is a fantastic and fun introduction to concepts such as above/below, inside/outside, visible/hidden, etc.
