1. Ghoul, not zombie : 2. It's a puzzle... you have to think to solve it. Grab from the tank that is labelled both newts and toads. Since every label is wrong @ start, then the one you just grabbed is the label you should put on the box. The box opposite to what you just grabbed cannot be the correct label you just put on the first box, nor can it be the incorrect label with which it starts. Therefore, put the label of "both" on that box. Put your last label on the last box, obviously. Assuming you grabbed a newt from the fake "both" box, here's a diagram: EDIT: Pssh, in the time it took for me to write that, you already solved it. xD
