Sell-itself Berries are a type of living berries that, as their name says, can actually sell themselves without Gazpacho. Gazpacho let the berries be in charge in Gazpacho Stands Up so he could think of Jokes with Chowder. The Sell-Itself berries look like blackberries with eyes, mouths, arms, legs and are blue.
"Oh, I don't know. I got the stand to look after. Fruit doesn't sell itself.... except the sell itself berries. Okay, you guys are in charge."
-Gazpacho, upon hearing the berries yell, "buy me, buy me, buy me!"
