Grape Jelly

The Grape Jelly was a product of the Napa Valley Vineyard that Nerville was asked to taste. Nerville went ahead and tasted it, and he enjoyed it so much that he asked for more. While Orange and the gang were trying to save a vine of grapes, Nerville remained in the tasting room eating jelly sandwiches. Towards the end of the episode, it was made clear that Nerville began to become obsessed with the jelly, but he paid no regard to his symptoms.
