Soon, the Smurfs hold a party, but a lot of attractions there appear to be sabotaged. The police force search in vain for the perpetrator, but with a trap Papa Smurf knows how to identify the culprit: there is only one Smurf who creates lanterns for the parties. He is tired of not being recognized, and because of that, the police can only have him pay fines while some others are let off the hook. The Smurfs forgive him, who now has the nickname "Lantern Smurf".
