"OH, GETAFIX!" shouted Asterix.

"OUCH!" came the cry from the top of an oak tree and a white bearded head popped out from behind a branch, "How many times have I told you never to shout when I am up a tree, I've gone and cut myself with my sickle!"

"Sorry" said Asterix, shamed. "Anyway, I've an old friend to see you!" and he pointed at the Doctor

"Goodness me, it's not is it?" said Getafix

The Doctor bowed, "Guilty as charged!"

Getafix made his way down to the ground and shook the Doctor's hand. "Would you like to see what we've been up to?" he asked

"Indeed" replied the Doctor, "in fact Asterix was going to tell us about it himself!"

"Then let an expert tell you" smiled Getafix and he led them all towards a small cave.

In the middle of the cave, there was a small cauldron bubbling away. "In this cauldron lies the potion that gives us our magic powers. This potion will increase the strength of whoever drinks by a thousand fold!" said Getafix, stirring the cauldron's contents.

The Doctor whistled impressively. "Not bad at all!" he said, "I suppose that the recipe is a closely guarded secret?"

"Indeed it is", said Getafix, "and may only be handed down to another druid, all I can tell you is that there is mistletoe and lobster in it! The lobster is of course optional!"

"Can I have some?" asked Obelix, as Getafix poured some of the potion into a small bowl.

"No, no, and for the umpteenth time, no!" said Getafix harshly

"Why not?" asked Turlough

"He fell into the first batch I ever made and it had a permanent effect on him. I daren't give him anymore for fear of something awful happening to him!" said Getafix handing the potion to Asterix who in turn handed it to Turlough

"You expect me to drink this?" asked Turlough. Everyone bar Obelix nodded. "But Doctor, it's got mistletoe in it and."

The Doctor turned to Turlough and stamped on his foot. Turlough screamed in pain and the Doctor poured the potion into his mouth.

"Doctor!" said Turlough, half coughing, "why did you do that?"

"Go on" said Getafix, "See what you can do for us?"

Turlough jumped up and down several times for no reason and then shot out of the cave like a rocket. All that could be seen of him was a blur as he ran through the forest at nearly the speed of sound. He stopped dead in front of a tree looking bewildered.

"Turlough" shouted the Doctor from the cave entrance, "be a good assistant and pull that tree up would you, it's blocking the view!"

Before Turlough could react, he found himself grabbing both sides of a massive oak and effortlessly pulling it out of the ground, he then rushed to another one and knocked it over with his foot. After creating a clearing in the forest around the druid's cave he picked up one of the trunks and cracked it over his knee and then ran back to the entrance of the cave.

The Doctor, Asterix and Getafix had collapsed in peals of laughter. "Well done, Getafix" said the Doctor, recovering. "I feel sorry for those Romans" Getafix said, "I really do" as he went back inside and gave Asterix a dose of the potion.
