Smurfs 1

When a strange fly bites one of the Smurfs, a full-on epidemic develops in the Smurf Village! After being bit, a Smurf turns purple and his vocabulary is reduced to one single word: "gnap!" The purple Smurf runs around the Smurf Village biting other Smurfs on the tail, causing them to turn purple and act crazy too! It's up to Papa Smurf to find a cure and save the Smurf Village before all of the Smurfs lose their minds for good!
