     "Um... Luna, are you sure you know where we're goin'?"
"Sweetie Belle, that's the fifth time you've asked, and the answer is as usual, yes..."
Sweetie Belle shivered when a sudden cold wind rushed past them. Her green eyes scanned her surroundings desperately and worriedly. It couldn't be a ghost -- can it?
Sweetie Belle was told that whenever somepony feels a cold wind pass thorough, that means that a ghost has floated past. 
The unicorn filly never believed in supernatural stuff, which she thinks it's all mumbo jumbo, make believe to be exact. however, on a day like today - she reconsidered whether ghosts are an old mare's tale anymore.
As the cave's floor was rough and bumpy, there was a high chance that she might trip over. Sweetie Belle tried to be more careful when she walked. Jumping over stones, leaping over boulders (small ones) and tip toeing over sharp edged stones. 
Luna was strolling when she suddenly stopped.
"Why'd you stop?"
Luna turned her head to face the curious white unicorn filly and spoke in a serious tone:
"There are many strange and dangerous creatures living here in this very cave. Whatever you do, don't wander off on your own."
"O -- okay."
Luna gave her an eerie smile and patted her little head. 
"Good filly."
Sweetie Belle giggled nervously. Something was definitely wrong with Luna.

Fluttershy quivered like a leaf in fear. Even though they have not ventured a mile deep in the cave, she looked like she would snap into two like a twig. 
"Umph -- umph... ca -- can I st -- stay here while you go find Sweetie Belle...?"
"C'mon Fluttershy! Don't be such a scardy cat! What did you come here for? Now get those hooves going!" Rainbow lamented, pushing Fluttershy into the cave. The dirt was flying in all directions as fluttershy's hooves flailed desperately.
Twilight sighed in annoyance, staring at the two bickering ponies. Twilight used her magic to levitate Fluttershy, and then trotted into the cave. Rainbow landed on the dirt floor on her face with a thud. Rainbow got up and spitted out the dirt in her mouth, like an unsatisfied animal spitting out its food that was served to it.
"Eww, gross." Rainbow complained, disgusted.
"Hurry up Rainbow!" Applejack called to the pegasus, who groaned and reluctantly trailed along behind the gang.
The cave was definitely not welcoming. It was pitch dark, bats flapping its wings could be heard, strange cricketing filling up the empty space of the cave and squishing noises from walking creatures. Fluttershy was quivering like a leaf in fear. She wanted to rescue Sweetie Belle and get out of here -- quickly.
****************************************************************************
"Here it is, Sweetie Belle." Luna declared to her. After a day of travelling, it was all worth it. There it laid the heart's desire in full bloom. Its vibrant petals glowing softly.
Sweetie Belle's emerald eyes gleamed in awe and excitement. She couldn't wait to get started!
"Oh, oh! Luna! Let's start, shall we?"
"Of courssse we can. Jussst follow me." Luna hissed, with a tingle of evil in her voice. The unicorn filly shivered and managed to flash a weak smile.
A soon as Sweetie Belle reached close enough to the flower, Luna's eyes and horn flashed brilliant green.  Shadows started looming around the cave. Suddenly, a black figure lashed out at Sweetie Belle. She yelped in surprise. Her eyes widened in horror.
It was a changeling.
