Well I bought more candy pebbles of all places, Wal-mart. Here is the directions in pictures.
As you can see, the candy pebbles started dissolving and at this point I am saying FORGET THE PEBBLES! Next time I am just going to use liquid food color. This time I used Americolor Sky Blue..just a tiny drop.
Oh and for the fun of it, I got out my food markers and had fun with a teddy graham.
