A new exchange student is introduced to the class named Jemmica, a girl in adventuer gear who proclaims herself as an amateur archeologist. She befriends the girls and request their help in finding a rare artifact. However the girls so learn their new "friend" is anything but and using them for her own ends.
Tropes:
- Bitch in Sheep's Clothing: Jemmica starts off friendly enough but once she gets the first of the golden idol, it doesn't take long for her to drop the facade.
- Continuity Nod: Buttercup mentions she still hates spiders.
- Karma Houdini: Despite the girls preventing her from getting the idols, Jemmica gets away and plots to pull the same scam at a foreign school.
- Ooh, Me Accent's Slipping: Jemmica makes Buttercup talk with a British accent. It's quite dreadful.
- People Puppets: Jemmica is able to trick the girls into wearing necklaces that will force them to do whatever she asks of them. However when she tries to force them to save the idols over the Professor, their desire to save their father wins out and breaks the spell.
- Shout-Out: Most the ep is one to the Indiana Jones series.
- Why Did It Have to Be Snakes?: Said word for word by Buttercup when they explore the ruins and run into spiders.
