This team is made up of the new 2016 blood bowl skaven team. To get the 4 gutter runners I needed to buy a second box. But I managed to recover a lot of the cost by selling the remaining models on eBay.
To get variety in models I have done some minor modding with felt tip pens for pipes, and added slime with clear adhesive UHU. I cut out clear plastic to a small point then used the adhesive to dribble/cover it.
The Skaven are spit into a few skin colours to further separate the models.
