Over on the Hub's main website, the Canterlot Creator game has had a whole pile of new updates added, including a bunch of new vectors from Nightmare Night. The big new addition is of course, Derpy. Our favorite paper bag-wearing mailmare has her own specialized vector in the game. That's pretty amazing considering she is the only additional pony outside of the mane 5/CmC/Luna.
Her filename even says "Derpy". I guess that disqualifies Ditzy Doo?
Check the game out here! And thanks to Whatshisgame for the discovery!
