Except for in a real scenario.. the 'stupid' rabbit wouldn't only be basing it only on the box... he also would be basing it on the pieces. It's not reasonable that he would see pieces that look like water and grass and not realize that it's a pond.
Plus the 'logical' rabbit would have determined it was a pond with Pooh as well.
If the rabbits were wondering how the pieces got there- the pic would have related to the religious debate.
One rabbit would have concluded that, some how, the material of the table formulated the pieces for them to put together. Somehow the wood turned into puzzle pieces. The other rabbit.. might conclude that maybe a human dumped them out the box onto the table.
