Once again, our beloved Smurf friends have to find a way to elude Gargamel's evil plans! In his dark laboratory, the evil wizard Gargamel has discovered a formula allowing him to create a wicked plant, called Vileaf. This plant produces “Viletrap” seeds, which can attract Smurfs and imprison them in vegetal traps! But these Viletrap plants are also a great danger for the forest, as they are highly toxic, especially for the sarsaparilla fields!
