Prune juice

Prune juice is a beverage created by Vino Smurf and served by Tapper in the EMPATH: The Luckiest Smurf story series. It is usually consumed by Hefty Smurf, with very few other Smurfs wanting to drink it due to its taste and the fact that it makes Smurfs go to the outhouse. Interestingly, prune juice is usually prescribed by Papa Smurf for dealing with constipation.
