Micah's 3rd birthday party was train-themed.
Train whistles from the pinata. 
There were plenty of train tracks to set up and destroy!
The train birthday cake
This cake was the easiest thing to make! I bought a kit that has silicone cupcake shapes and it tells you how to piece it together so you can make a train (or a rocket ship or a dump truck) and after you assemble and bake it, you decorate and voila! It's a train cake!
