Synopsis

At their first riding lesson, Sesame and Maddy are watching Silver
being re-shod, when they're whisked back to Karisma to
hunt for another magical charm. But they're up against Zorgan
the sorcerer and his wicked pixie puppets, Nix and Dina.
Treacherous Zorgan has raised the spirit of the dragon Agapogo
who guards the fabled silver pool. Now the pool has dried up
there's no more silver and the Silversmith and Queen Charm are
in despair.

And when there are charms to find, evil Morbrecia, the queen's
older sister, and her gribblers are on the trail. The race is on to
find the charms which will restore order and harmony
to the kingdom.
