Filthy Rich

Filthy Rich is Diamond Tiara's father and is seen in the episode Family Appreciation Day.

History
His grandfather, Stinking Rich, was one of the first ponies to buy Granny Smith's Zap Apple Jam. He makes a business out of selling them, which helps to contribute to the foundation of Ponyville.

In the episode Family Appreciation Day, he appears on Sweet Apple Acres with the intention of continuing this business and buying Zap Apple Jam from Granny Smith. He is later seen giving a presentation to Apple Bloom's class about his business in the Family Appreciation Day presentation, and he is again seen at the end of the episode pushing a reluctant Diamond Tiara to Sweet Apple Acres to help other fillies sing to the watering cans, part of the process of making Zap Apple Jam.
