Mike exited the space ship quietly; none of the creatures that were swarming over the ship took any notice of him. He carried a rifle similar to the ones the soldiers had. He set off through the jungle, unsure of where he was going. But the creature knew, the creature was going to find the soldiers and kill them all, one by one.
The Doctor was studying the creature's dead body. He'd materialised the TARDIS next to it and then put the TARDIS back into orbit. He had once again analysed it with the sonic screwdriver and was know reading off the details after plugging it into the console.
"So, what have you found?" Anna asked.
"I'm not sure but there's something in its brain that I've never seen before," the Doctor said, "It looks like it might be subconscious instructions for something."
"What for?" Rose asked.
"I don't know just yet," the Doctor said, "It might be easier to find out if I could find this creature in the TARDIS data banks."
"So you don't even know what this thing is then," Anna said.
"Nope, no idea at all," the Doctor replied, "All I know is that it's really ugly and smells."
"That might be because it's dead," Rose said.
"Fair point," the Doctor said, "Chuck it out of the waste disposal hatch."
"And where might that be?" Rose asked.
"Ah…I don't know," the Doctor said.
The Captain was not in a good mood, he'd just heard Colonel Jilkins's report about losing those four people. He'd told Jilkins's that'd he'd be demoted by a long way if they weren't found. He then decided to go and look himself, taking with him a few officers from the bridge. He stood outside the ship, taking in the surroundings. Nothing but greenery and squawking animals. Then he thought that it might be a lot harder finding four people here then he'd realised. Then something fell on him, knocking him to the ground. They all looked up to see the TARDIS hovering in mid air above them, the Doctor was looking down on them through the open door.
"Sorry," he said, and then went back inside.
As the TARDIS materialised the Captain discovered that thing that had fallen on him was the creature's dead body.
The creature observed its surroundings through Mike's eyes. It had encountered and eliminated four of the soldiers. Know it was waiting for the perfect opportunity to ambush a group that were approaching him. The creature had noticed that each of the soldiers had a series of small spheres hanging from their belts. Closer inspection had shown that these were small explosives, and one blowing up would set off a chain reaction with any others in close proximity. They were in range now; the creature aimed the rifle, and then fired. The blast hit one of the explosives being carried, all the explosives on that soldier's belt, and the soldier standing next to him detonated. Nearly all the soldiers were killed in the explosions and the creature took the rest out with more rifle blasts. When they were all dead it continued on, always on the lookout for any soldiers, as he stepped over the bodies it picked up one of the surviving explosives, it might be useful later one.
The Doctor was still chuckling at the disposal of the creature, he was still working on the translation of the instructions he'd found in the creatures brain. It wasn't going very well. Rose and Anna were now both feeling particularly bored. The TARDIS was still in orbit and they both wanted to be doing something.
"I've got it," the Doctor shouted suddenly.
"What?" Rose asked.
"The instructions," the Doctor replied.
"Well what do they say?" Anna asked.
"They're like instructions for after death," the Doctor said, "It's telling the creature's mind to enter a different body."
"You mean like reincarnation?" Anna asked.
"Yes, but this doesn't enter a completely new body it enters one that's already in use, it has to take control of that body or its mind dies," the Doctor explained.
"That's a bit like a cuckoo I suppose," Rose said.
"That's a good comparison," the Doctor said, then set the TARDIS to dematerialise on the planet's surface.
The Captain forced his way through the foliage, cursing whenever he snagged his foot on a tree root and tripped over. The rest of his party were having the same difficulty. Then he pushed back a bunch of leaves and saw behind it a boy, holding an energy rifle. The captain only had time to shout retreat before Mike fired on them, killing them all.
The Doctor came out of the TARDIS holding a small energy blaster; Rose and Anna were holding the same sort. The blasters themselves weren't very powerful so they could only stun anybody they were used on. The Doctor has also given them a TARDIS locator to help them get back.
"Right, we're going to split into three and go looking for Mike," the Doctor said, "And don't hesitate to use those blasters on him."
"Ok," Rose and Anna both said and the three of them set off in different directions.
The Doctor continued on for a short while before he encountered Colonel Jilkins's group of soldiers.
Mike stood in the ship's control room, the bodies of its personal lying against the controls or on the floor. Mike was setting the ships automatic pilot controls. At the same time he was planting a series of the small explosives everywhere on the ship, making sure that as many as possible were in vital areas. He'd placed several in the main power source of the ship. He then disembarked and placed several more explosives on the underside of the hull. After a few seconds the ship took off. Across the jungle the soldiers looked up to see it going without them. The Doctor took this as an opportunity to slip away from Colonel Jilkins's quietly. Then Mike aimed the rifle at the ship and fired at one of the explosives. The entire ship was destroyed as all the explosives detonated in reaction to the first one. Everyone on the ground ducked for cover as chucks of the ship rained down on them. The creature was satisfied with this; anyone on board that he'd missed would be dead. Now for those that were still alive.
