Sour Grapes

The Sour Grapes are the main antagonists of the episode Escape from the Planet of the Grapes of Wrath. They lived in the vineyard and spoke with French accents. They were not willing to let any of the other grapes leave their domain and would stop at nothing to keep them in check. When they encountered Orange and company, they started spitting seeds and sour juice at them. Finally, after they had given all they had, Orange was able to knock the raisins off of their vine and onto the ground. However, they were retrieved and sold outside the Grape Juicery.
