I bought a kit through Lego. I set up the table with a bowl full of legos, stickers and kits. They spent most of the time building things.
Lego Cake: angel food or pound cake rectangles marshmallows icing Lego Characters 1. Cut circles out top of cake. Place marshmallow inside, sticking up a bit. 2. Choose food coloring of choice and mix with icing. 3. Decorate with character. I let Noah decorate his own cake like he wanted. Not the way i would have chosen, but it's all for him anyway. :)
