Trollz

Ruby, feeling Amethyst upstages her, kicks her out of the group, leaving the other friends to try to reunite them.

The five friends try their hand at being magicians, but it has unpleasant consequences: the girls meet the mysterious obsidian.

The girls inadvertently release the evil Snarf from the Ancient World and have no idea how to get him back there.

The girls discover that their belly gems are dimming, so they must escape Simon the Gremlin to bring back the glow.

When Topaz's confidence wanes during the gym class, Simon takes advantage of the weak moment and takes hold of her body; his plan was actually perfect and Trollz-safe, but his arrogant demeanour destroys his plan.

On the evening before their big final exam in chemistry, the BFFL girls have to pass a much more difficult test: Simon returns to take revenge; Saphir helps the girls break a code during a nightly tutoring session.
