The leak was mainly just "they're upside down on a shuruken", so I took some liberties to make that look cool or at least decent. To make the upsidedown thing make sense, They're using their now way bigger tongue to suspend themselves. Speaking of which, I wanted to keep the theme of megas being goofy, and had Greninja's tongue just get stupidly bigger, like them hanging upsidedown was morso an unintended side effect and they made it look cool.
(There isn't a mega tag, so I just used the fakemon one)
