I did a Spongbob Square Pants Sandwich for my daughter today. But! She couldn't tell it's Spongebob!! :\ She said it looked like a cracker with face!! LOL I did the best I could. :P
If you are curious how I made the blue part of the eyes, I actually mixed a tiny drop of blue food colouring to some egg white and cooked. That did the trick. ;) The white part of the eyes and teeth are egg white. The pupil and the eye lashes are made from seaweed. The rest are cheese.
