Yeah I think it's pretty accurate to dress Pinkie Pie up in a skeleton costume because she is always so bubbly. I attempted to bring some darkness her way but it seems that no matter how much black she wears, she will always remain bright and full of life. Here is my take on drawing a Halloween version of Pinkie Pie. I couldn't possibly draw Pinkie with a frown or scary face because it just wouldn't look right. I hope you like my costume choice for her and remember, if there is any characters you would like to see transformed into a costume let me know.
