Filthy Rich won’t stop bragging about how he’s bought out practically every business in Ponyville, and even Diamond Tiara is becoming annoyed. The spoiled filly wishes she could do something to keep her family from giving itself a bad name. The good news is, she comes up with the perfect plan. The bad news is, she'll need the Cutie Mark Crusaders help.

And even the most brilliant of plans have a bad way of backfiring.
