It was a warm sunny day, Daniela, Lola and Ethan were getting ready to go to uni. They looked completely normal but underneath their skin was a giant 8ft tall slitheen. With their disguises no one would know, that was the beauty of it. The only side effect was the gas exchange, but after a few days of adjusting to human life, they were used to it.

Lola applied her make up to her face, her brown eyes shining in the mirror. She was a brunette and attracted a lot of the lads, but farting kept away any unwanted attention.

Daniela cooked them all breakfast using the remains of the other roommates they had hunted over previous nights. The slitheen now had the house to themselves.

They took the bus to the university campus, it was an awful ride for them, the walk to the bus stop was meant their skins would chafe, as soon as they got on the bus and sat down, they would usually fart, much to the displeasure of the other travellers. This time they got off and headed to their lecture.

They were in a biology lecture, their lecturer, Jenny, was the sort of teacher every lad liked, she would usually get 100% attendance from men in her class. This was because she was hot, and she knew it, she was also single and several lads thought they stood a chance.

The trio of slitheen arrived to the lecture late and sat at the back. They paid little attention to the lecture, instead they just eyed up people to hunt later, they knew it all anyway. Earth was a primitive planet and their science lacked that of the slitheen.

The lecture dragged on for two hours, before it finally ended and the class dismissed. However, the trio stayed at the back. Once the last person had left the lecture theatre the atmosphere improved.

Jenny spoke up: "Goodbye horny teenagers until tomorrow."

The trio moved down to the front row of seats.

Jenny: "Ah great choice of skins, you look incredibly human.

"Two of you are in my class, I recognise Daniela and Ethan, they were good students of mine, but who is this?"

Lola: "Her name was Lola and she was Ethan's girlfriend, I don't know what course she did."

Jenny smiled and said: "That doesn't matter I can transfer her on to this course using the uni system."

At the moment Jenny farted in front of them.

Jenny: "Ohhh yeah, I was holding that one in all through that lecture. Right are we ready to do a test run, I have got it all ready."

The three of them nodded their heads and followed Jenny down the corridor to a secret room. Inside was a tonne of alien machines and computers. The slitheen were just a one group, of many, that had infiltrated the planet at the same time. They planned to avenge the deaths of the Jocrassa, and those who fell in 10 Downing Street. Their leader Glune had infiltrated a school in London and was to lead the charge in turning off the sun.

Jenny: "Right synchronise the mega wattage.

Daniela: "Mega wattage synchronised."

Ethan: "Energy levels maximum."

Lola: "Test is looking like a success."

The three slitheen huddled together as they watched the sparks fly around the room, they laughed as they were one step closer to avenging their family.

Jenny turned off the machine.

Jenny: "Everything is going well, if we keep running so smoothly, soon the family will be avenged."
