Cheating works. I really wanted to solve this myslef since it seemed like a cool riddle but I couldn't with only one statue giving clues. So I cheated. I don't have the answers on me but I will add to this thread with the answers that worked for me when I can.
This mission is not required to beat the game but is required to get the Castle Crashers achievement for Xbox 360 so I imagine Larian might want to fix this one.
