(Catherine slitheen will now be referred to as Mia slitheen)

Mia "What do you think? How do I look?

She started to stut up and down the room as if showing off a new wardrobe.

Ethan: "How does she feel?

Mia "Better than expected. I have a nice rear booty.

She began to shake her bum up and down, as much as her tight jeans would allow

Mia "Hold on, I need to fart."

Pppprrrraaaaaaaaaaaaap

at that moment a wet fart came out of Mia's arse. Sofia went over to help Mia adjust Mia's skin and straighten up her clothes.

Sofia: "Don't you think we should fix the gas exchange, it's getting hard to hide.

Mia "It is a human thing, being human is just people farting, we blend in.

Ethan: "What should be do with Catherine , she was a good skin.

Sofia: "We could sell her back on raxo.

Mia: "I don't think there's any need for that."

She picked up Catherine 's skin suit, and opened a window. She through the skin out of the window, it glided down into a wheely bin below.

Pffffrrrrrraaaaapppptttt! Blllffffraapppttt

Mia farted again

Mia "I enjoyed being Catherine , but she's nothing but waste now.

Ethan: "Back to work, we have a signal to send out, we must advertise this god forsaken rock to the galaxy.

The three slitheen exited the office in their skins and walked down the corridor to a strange unmarked room. They entered. Inside there was a huge transmitter, capable of beaming a signal out to space.

Ethan: "Is the advertisement ready?

Sofia: "Yes its ready to broadcast"

Ethan: "Now we need to switch on the diversion.

Ethan walked over to a machine and pressed a button, it came to life and started up. Mia entered a code.

Mia "It should be broadcasting from the north sea, they will never think to look here."

The system loaded up and started pinging, the advert was live and the sale was on.

The three of them gathered and watched as the signal started broadcasting across the galaxy.

Ethan: "Let Blon know the signal is out and we wait until the family is summoned"

Sofia: "Then we can finally be done with pretending to be human"

Mia "Oh this poor girl is chafing as much as Catherine did"

The next day the slitheen were ready. Mia came into the office. Emma and Beth were already there.

Emma: "Good morning Mia, what's it like being promoted?

Mia "Oh its great, I've just come to clear my desk I'm moving to Ethan's office"

At that moment a wet fart ripped through her arse

Mia "Oh excuse me, I went for a celebratory curry last night"

Emma: "Oh you're already acting like them"

Beth: "That stinks, I'm getting my spray."

She sprayed the air, Mia started to sweat and have a negative reaction. The slitheen inside her was choking.

Beth: "Oh my god, I didn't think you'd have that reaction, are you okay?

Mia "Its just an allergic reaction."

She waddled off to the toilets.

Just then Sofia came in

Sofia: "What's happening in here"

Emma: "Nothing, we were just clearing the air and didn't think that she would react.

Sofia: "I will have to report this to the boss, this is why we didn't promote any of you."

Mia and Sofia headed back to Ethan's office. Mia had recovered from her reaction to the chemicals.

Ethan: "Do you ladies fancy a final hunt before we meet the family?

Mia and Sofia both smiled

Sofia: "I was thinking the same thing

Mia "Revenge."

The three of them devised a plan to kill the remaining staff.
