Smurfs #1: The Purple Smurfs, The (The Smurfs)

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! Soon enough, there are more purple Smurfs than blue Smurfs in the village. 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!
