Glue a roll of Life Savers to the top of a pack of gum for the base of the locomotive.
Glue on 4 peppermint candy wheels.
Glue 3 mini candy bars together in a stack. Now glue the stack to one end of the Life Savers for the engineers room. (Note: I added an extra mini candy bar on the back because I liked the way it looked)
Glue a Hershey's Kiss on the other end for the smoke stack. And there you have it, a cute little candy train!
