I've got one, My oc Harmony Star, is the conductor of the friendship express for a day, and is leading the mane 6 off to Canterlot. unfortunately since the whistle broke, he doesn't mind though, he had an idea by using the tip of his horn to blow off some steam, with smile on his face.
The look on Rainbow Dash's face says it all. "Thanks for the free sauna, Pinkie Pie! My crotch needed that!"
