"We disturbed his peace, now we'll share his tomb"
To quote Parker from this extra episode that was shown today here in the UK.
It all takes place in a mysterious pyramid built into the side of a mountain which is filled with dozens secret passages and booby traps to trap the unwary.
Enter Lady Penelope, Parker, Gordon Tracy and the dodgy Professor Harold, who is voiced by none other than original Thunderbirds voice artist Matt Zimmerman.
Thunderbirds 1 & 2 are the featured vehicles but it's Lady P, Parker and Gordon who steal the show for me.
It's an entertaining plot, but yet another which deals with the rescue of members of International Rescue. A high point for some will be a little more charactisation towards the end of the episode.
