Last year I did a Ben 10 cake out of a wig head.. http://www.cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1312220
The part I found the hardest was his hair. I had no idea how to make it look more like hair. Well this year my son wants Dan from Bakugan http://images.google.com/imgres?imgurl=http://www.bakugandojo.com/wp-content/uploads/dan-kuso.jpg&imgrefurl=http://www.bakugandojo.com/toys/dan-kuso-and-drago-pyrus-dragonoid&usg=__clcjXs_Qcepv5fP3ehoOQn7Qd3s=&h=776&w=600&sz=82&hl=en&start=5&um=1&itbs=1&tbnid=MbCz52LZBDPlvM:&tbnh=142&tbnw=110&prev=/images%3Fq%3Ddan%2Bbakugan%26hl%3Den%26rlz%3D1R2GPEA_en%26sa%3DN%26um%3D1....
I have no idea how to go about doing his hair. Any ideas would be GREAT!!!
I don't know how well this idea would work or not but if I was doing that cake I would try to do the hair with modeling chocolate. Just an idea. Maybe someone else has a different idea for you. Good Luck.
