Oh wow that take's me back. Nice red version referance though Derpy should have ran away from it if she had she could have gotten 99 muffins! Well if she had muffins in the third spot in her bag at least.
You know, it's funny. Both MissingNo and Derpy were both animation glitches (Derpy's face was apparently supposed to be hidden behind another background pony) who despite never having been planned to exist by their creators absolutely broke out in popularity and endless fanon. I'd be curious to know if that had been your intention in pairing them.
Seriously though, this absolutely made me break down laughing the first time I saw it. Well done.
