Berryshine
Berryshine loves berries more than any pony!
Each morning started the same for Berryshine. The purple unicorn would wake up bright and early. She headed downstairs to the kitchen and started to whip up that morning's berry pancakes. And then she was greeted by a loud "STOP CLANGING THE BUCKING DISHES!" from the living room.
She turned to face her twin sister, Berry Punch. Despite being her twin, this other Berry was an earth pony. And beyond that, she was an alcoholic. Berryshine did her best to take care of Punch, but when her sister came dragging home just as Celestia raised the sun each day and acted like Berryshine was the bad one for being awake in the morning…it was hard to deal with her.
"If you would come home and sleep at a decent hour, maybe my morning wouldn't seem so loud to you," she said calmly.
"You just don't get it," Punch said, clearly tired of the same argument again. Berryshine didn't understand her, didn't know how fun it was, and Berryshine was tired of hearing the same argument.
Berryshine sat beside her sister, gently nuzzling her to try and get her to sit up. "Punchie, you have a problem. Please, just try laying off the cider one day, okay?"
"Cider's good," Punch said. She was still draped on her side, so her voice was muffled against the couch cushion.
"But not good for you," Berryshine said. "Punchie, you know I love you, but you need to stop. Remember when you thought the house was moving?"
"Big Mac really was pulling it!" Berry Punch insisted. "And then he put it back after he jumped in a hole with Cheerilee!"
"That's ridiculous," Berryshine said firmly. "You were drunk and you know it. At three in the afternoon, and it wasn't even cider season!"
"I bought Applejack's extra," her sister replied. "There's still some in the basement."
The griddle was more than hot enough to start the berry pancakes, but when Berryshine stood up, she headed straight to the basement. She came out with a jug of cider held tight in her magic.
"What're you doing with that?" Punch asked suspiciously.
Berryshine answered by dumping every last drop of cider down the sink.
"Stop!" Punch cried, but Berryshine dropped the cider so she could focus her magic on grabbing her sister's tail. The earth pony was forced to sit back on the couch, though she still reached for the cider draining away.
"You don't need this," Berryshine said. "Come on. I'll make you pancakes."
"Berry pancakes?"
"What other kind is there?" She walked over to her sister and gave her a quick nuzzle on the forehead. "I'm gonna help you buck this, Punchie. I promise."
