My little boy loves the movie "Cars" and wanted that theme for his 3rd birthday party. We had a party just with family because, hey, he's only 3. Also it was on a Sunday after church, which is why everyone is all dressed up.
We started with a rousing game of red light, green light.
Then I printed out a "Don't eat Pete" game board with pictures of all the "Cars" characters on it instead of faces. To play "Don't eat Pete", you put a small food like m&ms or marshmallows or cheerios on each square. One person closes their eyes while the others choose which square is Pete. Then the first player opens their eyes and starts eating, a square at a time, and when they pick up the piece of food on the square designated as "Pete" everyone yells "Don't Eat Pete!" at them and their turn is over.
For our last game, we raced laundry basket "cars". The dads helped push the kiddos across the room. Everyone had 3 or 4 turns. Very fun.
The cake wasn't spectacular, but it worked. Christopher enjoyed being able to keep the cars on top.
