Rainbow Dash is actually a member of an Alien Species known as the Radugu Desch. They are all Rainbow Dash. Their Leader is Big Rainbow Dash. They have come here in their Spaceship (Also Rainbow Dash) for the most Rainbow Dash sport in the Galaxy (NASCAR)
If you think about it they really are aliens, just magic aliens from an alternate reality with different laws of physics
Can we see Winnie dressed for the holidays again this year? It warms the wolf inside!
