"It's a Yeti!" gasps Who.

As the ferocious beast approaches, the travellers turn back to face their time machine...only to find an horrendous Ice Warrior blocking their escape!

"I'll sort you out!" hollers Dodo Dupont as she drives home her attack! Head down ready for the kill, she charges at the green gilbert...

With the beast toppled, the brave threesome make good their escape - just as the Yeti is almost upon them. The TARDIS leaves the South Pole, heading off and away to safety...

Inside the spaceship, everyone relaxes with space buns and tea.

"Where are the time traces taking us to now Doctor?" enquires Steven.

"Well unless I'm very much mistaken my boy, someone has been diddling about with my instruments and we seem to be on pre-set co-ordinates..."

Suddenly, someone enters the control room from the sleeping quarters!

"A Cyberman!" gasps Dr Who. "He must have sneaked aboard the ship while our backs were turned!"

"It must have been him that set the controls!" deduces Steven.
