Ah, this will be a Terrorkon then. Large, red and angry. Like an enormous spot on the end of someone’s nose. Except with two heads. And teeth. And claws.

An underwater shot of the Daleks’ sub-aqua craft. In the script I dubbed them aquabouts, though the word is never heard on screen. Which is a mercy.

Deep in the bowels of the Dalek City lies a plumber’s worst nightmare...

If you squint, you can just see the Emperor and the Red Dalek by their hovercar. They’re heading towards that large pipe with the red top on it.

And here is the Emperor and the Red Dalek inside the aforementioned pipe.

The Terrorkon does battle with a giant eel.

Ooh, it’s just like all those Godzilla movies I used to watch as a child.

The Terrorkon clutches the missile as it advances into the heart of the mountain. I’m very pleased with the water in this shot.

Hovering in a natty spaceship within snapping distance of a Terrorkon’s jaws was considered an extreme sport on Skaro.

Actually, it would be an extreme sport no matter where you did it!

The Daleks love their gadgets almost as much as the Third Doctor, and this little ship is amongst my favourites.

The Emperor and the Red Dalek like nothing better than a good chin-wag. Despite not having chins to wag...

Daleks aboard a voltascope realise they may be in a spot of bother.

Note wishing to give anything away, here, but my guess is that the spot of bother is large and red with lots of teeth...

After a hard day of exterminating things, the Emperor and the Red Dalek enjoy watching a spot of telly.

Shame the aquatic adventure they’re watching is a repeat called ‘Exterminating Fish’.

I told you I like these ships... And here you can just make out a Dalek through the cockpit glass.

The Emperor and the Red Dalek prepare to hitch up their skirts and crawl through a pipe.

This has to be Sixties-style design at its most bizarre...

This is the missile that is causing all the kerfuffle. And as you can see, now it has a great big split in the casing.

If that thing goes off, there’ll be crispy fried Dalek on the menu tonight.

The Emperor and the Red Dalek share a quiet moment together in a cave somewhere not too far from the Lake of Mutations.

They knew these secret trysts had to end, but neither could bring himself to say the words...
