Maud Pie

Maud Pie, full name Maudelina Daisy Pie, is a female earth pony and a geologist. She is the daughter of Igneous Rock and Cloudy Quartz and the sister of Limestone Pie, Pinkie Pie, and Marble Pie. Her voice is monotone and her personality is rather bland, but Pinkie Pie knows her well enough to distinguish between her mannerisms.
