The episode that introduced the evil witch Hogatha to the series.
While the witch goes out flying with her pet vulture, Hogatha crash-lands in the forest and loses her magic amulet. Smurfette finds it when she goes looking for flowers to cheer Greedy up when he is sick and decides to wear it, not knowing that it is a magic amulet. When strange things start happening in the village, such as Jokey turning into a literal "philosophical giant", Grouchy suddenly becoming a cheerful Smurf, and Greedy turning into a fiddle, Smurfette suspects that it may be the amulet she's wearing that's causing the transformations and goes out into the forest to get rid of it. Meanwhile, Hogatha teams up with Gargamel in order to find her amulet, with Gargamel accidentally gaining possession of the amulet when Smurfette gets rid of it. While Hogatha uses the last of her magic to change herself into a frog so she could get the amulet from the Smurfs, Gargamel is already using it to capture Smurfs, which ultimately leads to a confrontation between the sorcerer and the witch near the end of the story. However, the Smurfs get a hold of the amulet and destroy it before either of the villains could do anything more with it, and with the destruction of the amulet, Hogatha seems to vanish as well.
This episode provides examples of:
- Amulet of Dependency: The magic amulet that grants Hogatha her magical powers as well as her existence.
- Be Careful What You Wish For: Though Smurfette didn't know that the amulet she was wearing would literally grant her wishes.
- Bewitched Amphibians: Hogatha disguises herself as a frog in order to infiltrate the village.
- Literal Metaphor: Greedy being "fit as a fiddle", and Jokey "growing up" and being serious.
