I am doing a riddle contest online… again. This is bad, because I’ll get stuck on a riddle and it will occupy my mind, nonstop, until I solve it. It drives me nuts. I finally had to quit, the last time I did this, because the obsession was overwhelming. And the riddles were getting too hard. Nonetheless, I find myself shamed to be stuck already, on the 5th riddle of round 1.

Click to see riddle… any suggestions?
