Episodes:
1. Thunder in Paradise: Part One
2. Thunder in Paradise: Part Two
3. Tug of War
4. Sea Quentin
5. Strange Bru
The first two episodes are a nice buried-treasure adventure that does a nice job of setting up the series.
In the third episode, the show's one recurring villain is introduced, who, in episode 4, continues to cause trouble in a cool underwater prison.
The fifth episode is an action-packed voodoo-oriented one with some quite good 'character development'.
