Original Description:
 
Twilight Sparkle landed down gently on her hooves, still the ground felt a shaking as she was massive and stood between buildings with almost not a single room fitting for her to get through. “Phew, that was close.” She said, as she made sure she didn’t step on anyone.
 
The citizens residing in London saw the giant alicorn in the city, initially thinking she is an enemy, but as she looked down smiling at them, they took her as an ally despite her size.
 
“Nice day today seeing you in this city, Princess Twilight!” The citizens said, greeting the giant pony with some other tinies waving at her. “It feels nice seeing you all, too.” Twilight Sparkle replied back, feeling accepted that the tinies love her as usual, no matter how big or small she was.
 
 
“You tinies could seem in the need for some help, right?” Twilight Sparkle asked the tinies, knowing that she could be a big helper.
 
“Sure do.” They responded, appreciating her offer for being a huge helper for them and the city.
 
Twilight Sparkle levitated humans at least three at a time, until her back was enough to carry ten tinies on her back. “Looks like I have no room filled for anymore humans.” She said, knowing that ten tinies is the limit for any humans having a ride on giant ponies.
 
The giant alicorn started her walk through the city and carefully walked her way through the city without stepping on a single person, though her front left hoof accidentally knocked one of the buildings, but only minor damage was caused.
 
“Oops, I didn’t see that coming.” Twilight Sparkle said, looking a bit guilty over a building accidentally being knocked over by one of her hooves while she continued stomping her way through the city while attempting not to make another accident any further.
