Infiltration

"Slitheen can infiltrate planets by hiding in the skins of the dominent native species!"

- Sarah Jane Smith

Infiltration
To disguise themselves, the Slitheen squeeze into artificial body-suits, sealed with a hidden zip across the forehead. They use a compression field - controlled by a device worn around the neck - to make their bodies fit inside the suits. Being so large, they can only shrink down far enough to impersonate very large people. This also results in copious amounts of loud farting, known by the Slitheen family as gas exchange.

The technology of the compression field was improved so they can now shrink into thin and skinny people without gas exchange.

When the suit is opened, pent-up energy is released with electrical flashes round the zip and blue electrical discharges from the body-suit. The body suit will get squished as the Slitheen exits out.



Noises
Slitheen can make noises while escaping their skin. In Ailens Of London and World War Three, the noise is a squelching noise for Asquith but a crackling noise for Margaret. In Boom Town, the noise is again is the crackling noise. In SJA, as an example, they tend to make squelching noises and moans.
