For Halloween I decided to be Vanellope Von Schweetz, aka President Fart-feathers, aka, Baroness Boogerface etc.
I love Wreck-It Ralph so I just had to be Vanellope Von Schweetz for Halloween! She's fun, she's crazy and she was perfect for me! Isn't it perfect! Penolopy is Venellope! I gathered information on her specifics on the Disney Wiki, but didn't follow it word for word of course :)
If you want to be Vanellope but just don't have time to make the costume, Amazon actually has a pretty cute version for sale :)
