Jessasaurus 

Jessasaurus is when a Jessica evolves into it's more aggressive form. Characterised by eyes halfing in size, red face and long sharp nails.

The Jessasaurus is rumoured to have originated in Essex, but, is said to be preying on people as far south as Bedfordshire.

If you come into contact with the jessaurus try to mesmerise it with herbal remidies until asleep, where the transformation will reverse.

Fuck me, she's a jessasaurus today!

RUN!!!! THATS THE JESSASAURUS.
