I made this Ben 10 And Wildmutt Birthday Cake for my grandson, a Ben 10 & Wildmutt fan. The base was a chocolate cake covered with butter icing. I copied pictures from the Internet and made separate templates for the body, hair, shirt and watch. I traced onto fondant, cut them out, then layered them onto cake.
The teeth and claws cut with a 104 icing tip. Used gel for eyes and part of watch. The watch also painted with silver powder. Hands, ears and other markings drawn with Sugar Art Pens.
My grandson and friends loved the cake.
Your Ben 10 is spot on, Amazing!!
