Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, Greedy makes jams, jellies, and preserves of all kinds of flavors: smurfberry, raspberry, blueberry, blackberry, strawberry, cherry, grape, and orange. Occasionally for Sloppy he will also make stinkberry and sourberry jelly. Iceberry jelly is usually made around winter as personal gifts for his fellow Smurfs.
