Blue Cars Cake

My son was insistent that he have a blue car cake for his birthday. He's a huge fan of Cars, so I went off one of his cars he had in his collection. I had to do the logo on the hood because that's what's on the hood of the winning car. I originally put a 3 on the car because my mommy brain went back to last years cake with a 3 on it, plus this one has both the 3 and the 4 on it, so I got confused. Fortunately frosting can be erased easily and I was able to fix the number on it before the party.
