Berry Punch, contrarily to popular belief, is not a drunkard of a mare. She might smell of alcohol but the reason behind it is blatantly shown by her cutie mark. She is a Brewmaster. No one knows a how to make a brew like Berry Punch does.

*EDIT: going through a shift in the plot of the story i had originally thought, instead of being a comedy, i'm going to turn this into a drama because i know of NO ONE who's made character development outside of Berry being a drunkard and damnit, if i'm going to be the one to develop her as a good character to the fandom, then by the 4 princesses of ponykind i swear i will turn her into somepony great*
