These are the facts for Raspberry Beret, one of the four members of Method Mares:

• She is the seventh Earth pony mare whose voice actress is Andrea Libman, following Pinkie Pie, Daisy (Season 2), Apple Leaves (Season 3), Hinny of the Hills (Season 4), Strawberry Ice and Chock-full Carafe (both also from Season 5). She is the fourth Manehattan pony who has the aforementioned voice actress.
• She is the second pony who has “Raspberry” somewhere in her name, following Raspberry Glaze (also from Season 5).
• She is the first and only pony who has “Beret” somewhere in her name.

This is one of the two ponies I’m doing today, along with On Stage.

There’s only a little more facts about her here
