“Hey! I thought it sounded really nice!” Sweetie growled. “Let’s hear you sing it then!”
Chrysalis sang.
“That was–”
“Amazing, wasn’t it?” Chrysalis tossed her mane cockily. “I have true talent.”
“It sounded as if you had thrown pebbles into a pasta roller and forced them through while you dunked a cat into the river repeatedly and used your magic to drag diamond dog claws down a blackboard.” Sweetie said. “I couldn’t recognize any of the words because they were destroyed immediately.”
“And that, filly is how you sing like a changeling,” Chrysalis grinned.
They stared at each other until Sweetie Belle spoke. “You’re lying.”
“I’m not!” Chrysalis raised a hoof to her chest. “Do I look like somechangeling who would lie?”
“Yes,” Sweetie Belle stated. “And changing your face to look like Applejack’s while leaving the rest of your body normal is really, really creepy.”
In a flash of green Chrysalis was back to normal. “Well fine, how did you know?”
“Just before you started singing you shape-shifted your ears away,” Sweetie Belle said. “And even then, I’m sure I saw you wince when you dislocated your jaw while attempting the third verse.”
Chrysalis cringed. That had been painful.
