Cherry Berry screamed as the might tyrannosaurus reached down for her with its tiny, mostly-useless arms. She shielded her face with her hooves, but the dinosaur stopped a few feet from her, flailing its tiny arms ineffectively and growling at its own poorly-evolved body. Cherry Berry ran for cover.
"Hold it right there, Mister Dinosaur!"
The terrible lizard king turned, raising one eyebrow at the sight of the yellow pegasus hovering nearby.
"What do you think you're doing, huh?"
The dino simply roared at her in response.
"Oh crap, maybe I can't speak dino. Um, sprechst du Deutsch?"
The dino whirled around, slapping Fluttershy with its mighty tail and sending her careening across ponyville, caroming off the bell tower, and cascading down a thatched roof. The dino cackled as well as a dinosaur could, which devolved into a series of coughs after a few seconds. It trudged through the wreckage, reaching for the nearby water tower to get a drink.
"Oh, no, you don't!"
The dino turned again, only to be punched in the face so hard that he forgot his own name (it was a stupid name, anyway). It groaned and tried to rub at its sore face, but couldn't reach. It looked up at Fluttershy, who was glaring at him with zero fear in her blue eyes. It reached up to bite her, but she simply slapped at its snout.
"No! Bad dinosaur."
It just roared again, but found Fluttershy's elbow dropping right down into its forehead with a bone-shattering crunch.
"I told you to stop terrorizing these poor ponies!" Fluttershy flew around behind the dino, wrapping her hooves around its neck and squeezing. "But you just wouldn't," she punctuated her sentence with a punch to the back of the head, "listen!"
She flew off toward a house, ricocheted off, and rocketed back at the dino to clothesline it right across its fat, green neck (because dinosaurs are green). The impact sent it stumbling back, but it stayed on its feet.
"Tough guy, huh?" Fluttershy slammed herself into its thick gut, lifted the dino up off the ground, and suplexed his head right into the dirt. The dino moaned, rubbing its head and neck, but Fluttershy wasn't done it it just yet. "Now, next time you want to come into Ponyville and eat everypony, don't!"
Fluttershy grabbed the dinosaur by the tail, spun him around, and hurled him off into the distance, where he later cried on the sympathetic shoulder of Queen Chrysalis just before she ate him.
