Pinkie Pie is an Aligater, you can tell by her familiar, and the magic she uses.
https://www.thefreedictionary.com/Alligate
She uses magic of places and connections to pull off her tricks. Her "stretching" is actually her shortening a space and reaching through, making her look distorted for an outside observer. She also uses it to outrun Rainbow Dash. She prances over a few yards while Dash races for a mile. "Pinkie Sense" is her sensing otherwise-undetected connections between events.
