Puckerberry

From Cartoon Network Wiki - The TOONS Wiki

A Puckerberry is so sour it lives you to your mouth. When you eat a Puckerberry, your mouth puckers than your eyes water, than you puck up in your mouth. The Puckerberrys and Puckerberry Overlord take over your mouth. The Puckerberrys own the taste buds. The only way to escape the Puckerberrys is to balance the sour with the sweet.
