The Mighty AtomEdit
Whilst holidaying on Tracy Island, Lady Penelope begs Jeff Tracy to let her go along on the mission to the Saharan Atomic Station. After he agrees (albeit with some reluctance), she joins Virgil and Gordon in Thunderbird 2.
A Mouse on BoardEdit
The Hood sends the Mighty Atom onto Thunderbird 2, to photograph the controls, but he is furious when he later discovers that the robotic mouse has instead taken pictures of Lady Penelope screaming at it!
