The components that made the item work would be scattered across time and space, and the girl of the series was required to travel and collect them all before T-Bag could get her hands on any of them.
Kellie Bright, who later appeared in The Upper Hand, The Archers and EastEnders, played Sally Simpkins in series five and six, plus a Christmas special.
In T-Bag and the Rings of Olympus, the heroine is the Goddess Athena's handmaiden, Polyzena, or Polly, played by Natalie Wood.
These are often historical settings or settings from folklore or literature, such as ancient Egypt, ancient Rome, Renaissance Italy and Elizabethan England, Tom Sawyer's American South, Robin Hood's Sherwood Forest or a French Foreign Legion station in North Africa which owes something to Beau Geste.
He would then team up with the girl, and the final episode would usually show T-Bag stealing the collected items back and being within striking distance of victory only to be thwarted at the last second and apparently destroyed, although this was usually temporary.
The departure of Tallulah and arrival of Tabatha also caused a role reversal in regards to T-Shirt, as he became more competent and level-headed against her silliness and tendency to rush into situations (to the point that, in Pearls of Wisdom, he was able to successfully deliver one of the titular pearls to T-Bag on two occasions, only for her to immediately lose it both times - not that it stopped her inevitably blaming him for her failure).
In the final episode of the series, she found that she had been on a wild goose chase while Granny Bag set up a surprise party for her during the distraction.
