This Spongebob cake was my first customer order cake so I was super excited!  I used a full sheet pan and crumb coated the cake before decorating it.  I used a toothpick to draw in the areas of the face and areas to outline.  I then outlined those areas in black icing.

I then tinted the remaining icing all the appropriate colors and used a star tip to fill in the areas except for the tie and white underneath it.  I used a red gel icing for the tie and used a round tip for the writing in blue.  The customer loved it so I was very happy!  Enjoy!
