Author's Notes: I do not own Doctor Who, the Doctor Donna or Hello Kitty. Thanks for reading and hope you enjoy.
The Doctor, Donna and Zara raced over to Hyde Park following the signal on the Doctor's Hello Kitty Timey Wimey Detector.
"Don't call it that!," the Doctor said to Donna as they raced in the park.
"If it's not a Hello Kitty Timey Wimey Detector, then why's it got Hello Kitty on it?"
"It had the parts I needed!"
"Don't be such a grouch. You can give it to Zara to detect Timey Wimey things when she gets to be a bit older!"
They tracked the energy signature to the Winter Wonderland portion of the park. The place was full of families trying to make the most of Christmas Eve. There was a wheel and carnival rides, a Christmas circus and an ice rink.
"What?," exclaimed the Doctor. "Why has no one ever taken me here? Is this new?"
"I'm sorry, I thought you were terrified of Christmas," said Donna.
"I am, but I like carousels. And ice skating! I haven't ice skated in centuries, Donna!"
"Singing!," shouted Zara.
The Doctor looked up at a group of carolers and was relieved to find they were all human as they sang a rendition of "Good King Wenceslas."
They went to seach farther and when they were in the Bavarian Village Donna was about through with it.
"Okay, Time Boy, where's Rudolph?"
"I don't understand, it's like the signature's moving. Every time I go to follow it, it's as if he's changed destinations."
"Biscuit!," said Zara.
"Zara, how can you think of food at a time like this?," asked the Doctor.
"Mummy!," said Zara.
"Mummy's got it, sweetheart," said Donna.
She steered the Doctor to one of the stalls selling German baked goods. She got biscuits and hot chocolates and they sat down at a nearby table.
"Here, Zara," said Donna, "I got you a gingerbread woman."
Zara looked at Donna suspiciously. She pointed at her hair.
"No, Zara, it's made with ginger, not of gingers," said the Doctor.
"Oh, that is ridiculous," said Donna. She looked back at Zara who still looked worried.
"It's not ridiculous, I find that most things I encounter turn out to be quite literal."
"Such as?," asked Donna.
"Well, 'We didn't have the parts' for starters," said the Doctor.
"What?"
The Doctor remembered he had once just narrowly escaped a full out explanation of his time with Madame de Pompadour. He decided not to press his luck. "Never mind."
Donna looked at Zara. "It's a spice, sweetheart. Here, Mummy will have a bite first."
Zara watched as Donna ate and joined in. The Doctor, having regained possession of his sonic screwdriver, tried to increase the accuracy of the Hello Kitty Timey Wimey Detector.
"The signal's stabilizing a bit, maybe I can get a better projection in a moment and we can follow him," said the Doctor.
"I'm starting to think I had it easy last pregnancy when you couldn't force me to run around chasing something."
"That pram's got really good suspension, though."
"Okay, time travelling reindeer, what do you think?"
"I don't know. Maybe it's a Time Reindeer? Time Deer?"
"Is there a such thing as Time Deer or are you just making up nonsense?"
"I'm just making it up, but there should be such a thing as Time Deer. That would be brilliant!"
"Sort of makes sense, though," said Donna.
"What part of it makes sense?"
Donna gave a cautious look at Zara. The little girl was watching her mother intently as she ate her biscuit.
"Well, Father Christmas is meant to visit all the children of the world on Christmas Eve, right?"
"Except for the ones Hanukkah Harry visits."
"Who is Hanukkah Harry?"
"Nice bloke. Lovely wife. She makes fantastic blintzes."
"You're putting me on?"
"I am most certainly not putting you on," said the Doctor. "I'll take you later. But, yes, Father Christmas is meant to visit all the children of the world in one night and the outlying colonies and the space stations and one sect of Ood that adopt Christianity."
"Christian Ood?"
"They got taken in by the whole Christmas thing. You should hear them carol. Donna, if you keep getting distracted by everything I say, you're never going to make your point."
Donna sighed. "The point is, that if he were to do that..." She cast a glance at Zara. "...because of course he does, wouldn't he need a time machine or something to go that many places in a single night?"
"Or a time stopper."
"What's a time stopper?"
"What's it sound like?"
Donna decided to ignore that. "Okay, but wouldn't he?"
"Suppose so, but that would be exhausting for a reindeer."
"Big doggie!," shouted Zara.
"Zara," he looked back at her to see she was pointing in the air.
The reindeer was flying. People in the crowd noticed and started pointing in awe and the children got absolutely giddy. There were shouts of "Rudolph" and delighted shrieks.
"It flies," said Donna.
"Uh-huh."
"IT. FLIES."
"I noticed."
The reindeer started showing off doing maneuvers and tricks in the air. The Doctor and Donna stood up.
"What's he doing?," asked Donna.
"I don't know," said the Doctor.
"Big doggie!," shouted Zara, clapping her hands in glee and making tiny screams of delight.
Then the Doctor noticed the reindeer was eyeing Zara, gauging her reaction.
"It's her! He's here for Zara!"
"What? You mean Rudolph's trying to kidnap my baby?," asked Donna. That really would be too much.
"No, I think he just wants to be her friend."
Rudolph did a loop and came in for a landing in front of the pram, lowering his head to Zara. She reached up and patted his muzzle.
"Good doggie," said Zara.
"That's why I couldn't track him! He's been looking for us!"
Donna then noticed there was quite a crowd forming around them and the flying red-nosed reindeer.
"Doctor, I don't suppose you have any ideas about what we're going to do next?"
"Well, we can't stay here," said the Doctor noticing the police approaching.
"Your plan is?," asked Donna eyeing the same police.
"Well, first you grab the pram."
Donna did. "Yeah?"
"Now grab my wrist."
Donna shook her head and used the hand not on the pram to take hold of his wrist. He grabbed Rudolph's reins with his other hand.
"We are not flying!," said Donna.
"Of course not." He shook the reins. "On Rudolph!"
The crowd watched in amazement as a reindeer, the Doctor, Donna and Zara blinked into a white light.
