Solution to 6: Monkey Tricks
This puzzle is missing the letters that you need on each petal. Some careful searching is needed to find the letters. Once you have found them, do as the puzzle says by adding the G to the word. Then, you have to rearrange the letters to make a sensible word.
1. Very faintly on the left-most petal - LYEE becomes ELEGY
2. Scrolling down and hidden as black text - AEEL becomes EAGLE
3. The name of the image - IRDI becomes RIGID
4. Changing the extension of the file from .jpg to .txt and scrolling to the bottom of the text - DENU becomes NUDGE
5. Looking at the page source, there is a comment - NIAA becomes AGAIN
6. On the page source, clicking the stylesheet.css file to find the comment - HODU becomes DOUGH
Lastly, take the first letter of each of these words and add in a G again to rearrange for the word grenade. Teams could have accidentally stumbled upon the words angered, derange, or enraged, but the message would tell you to use the G first.
Neither of us liked this one because we believe that with a good puzzle, what you see is what you get. However, this one was thrown in to appease those of you who like to search for hidden stuff.
