The snow crunched under Donna's boots and an icy wind whistled in her face. She turned back to the TARDIS, where the Doctor was emerging.
"I dunno what it is with you." she told him "You got a bit of a thing about ice planets?"
The Doctor looked injured. "Well, the last time was hardly a fun day out!"
Donna nodded. "Yeah, slave trading and weird tentacle-faced creatures. All in a day's work, though!"
Grinning, he wondered; "So, where first?" He peered through the blizzard. "Ooh, that looks interesting!" And he jogged off.
She sighed and set off after him.
Donna arrived in some sort of ice version of Stonehenge. Huge transparent megaliths towered above her, in a circle. The Doctor was crouched at the centre of the circle, glasses on, evidently examining something.
Donna wandered over to him "What's that, then?" she asked him. He turned round and grinned at her. "It's a great big BUTTON!!"
She stared at him. "So, whatcha gonna do?"
He smiled. "This!!" and banged his hand down on the button.
The earth shook beneath them. The megaliths began to sink, melting, and as she watched, so did all the snowy landscape.
She turned to the Doctor "What did you do?!"
"Well…" he began "This planet's supposed to be covered in water. I realised something was wrong as soon as I stepped out of the TARDIS. The megaliths were holding a large amount of heat, I let that go, and bam! This is the only land on a water planet!"
Laughing, Donna said, "So any inhabitants can go back to their normal lives?"
He nodded. "That's why I did it!"
Then she asked "So, clever-clogs, now you've finished saving yet another planet, answer me this: how do we get back to the TARDIS?"
"Oh."
