You must complete the game without entering ALERT phase once! Save frequently because if
you go into alert you must load the game and keep on trying!

You have to shoot all the hidden toy frogs after you do that steath will be in you're
backpack! Make sure you start a new game first. If you have a hard time finding them use
the thermal goggles or the binocualars! But don't forget to stay out of sight as well!
It's also a good idea to start looking in the virtuous as well! Don't move to the next
area until you find all of them in one area! Some areas don't have a toy frog in them! But
does not mean that you can't stop searching! Don't give up if you can't find one!
