Lego Cake being built by a Rice Krispy Treat Construction Crane

This cake was made for one of my daughter's classmates whose mother won a gift certificate that I donated for an auction for our daughter's school. He wanted a construction crane cake so I suggested making a crane and make it look like it was building a cake made from Lego's. I was told he loves Lego's so that is what I did. The cake was chocolate with vanilla buttercream/chocolate chip filling and the crane was made from Rice Krispy Treats. Everything was edible with the exception of the ladder and the tower like thingy (sorry but I don't know what to call it) which were made from wood skewers and painted with black food gel and the strings. Happy 4th Birthday Nicholas!
