My favorite model from GW is Skarsnik and Gobbla, the Warhammer Goblin leader with his faithful squig. I think the model is outstanding and recently won 10 th place in the top 25 Best Warhammer Models of all time.
I really wanted to use this squig in my 40K army, so I decided to add him as the third squig in my Tankbustas group. It worked out perfectly, because the unit comes with only two squigs in the box and they are allowed to have three.
I didn't do anything to him, besides changing his position and adding the explosive.
Very easy and great fun to look at once on the battlefield.
Imagine those poor I.G. soldiers when they see this yellow monster chasing after them..
