>>16266287horsefucker from /mlp/ since Season 1 here.
The reference could have been intended since the words 20, percent and cooler are in the same dialogue box.
BUT NO ONE on the fandom picked up the reference. It's just you anti-ponies being extremely delicate about the games "we" touch, plus the X and Y localization is filled with LE EBIN MAYMAYS so it's just paranoia.
Next thing you'll tell me is that Amaura is based on Rarity the unicorn (which is a very short-lived joke before actual game release).
