The Upper Middle Class Wildberry Kids are a group of young Wildberry People that Finn and Jake hire to guard their treasure in the episode, "Furniture & Meat." At first they decline because they're "upper middle class," but are then later convinced. They run away after being scared by the Homeless Wildberry People.
They appear to be a Blueberry, Raspberry, and a Strawberry. After receiving gold, they put on backwards hats and large, expensive shoes.
They seem to to favor money, as they are "Upper Middle Class." Despite this, they still seemed to be compliant to Finn and Jake's wishes.
- They are the only citizens in the episode whom didn't want the money.
