Pinkie Pie represents the element of laughter, but she isn't always so cheerful. She experiences depression, especially as a filly. Even now, she goes through unpredictable periods of extreme sadness. Or she would, at least, if it weren't for a certain mare. No pony besides Maud knows how often Pinkie Pie would fail to harness her element if it weren't for her. She provides Pinkie Pie with occasional doses of happiness disguised in the form of homemade cupcakes. The only downside is where she gets her main ingredient.
