The person she stumbled over? Was actually a fairly tall pony as he chuckled. "No worries, I wasn't looking where I was going."

He went over and held out a hoof for her to take. "You okay? You took a bit of a spill when you fell over me."

He was about half Selphie's size, not big, but strongly muscled.

Shining Armor was also a unicorn too.
