Continuing on the Squig Hopper theme, I've just finished painting the Night Goblin Big Boss on Giant Cave Squig. In the new book, this guy will be the only character able to join a unit of Squig Hoppers. The benefit of this Boss is not only his added combat proweness, but also his ability to re-roll the Squig movement. Also, if he's leading other Squig Hoppers, he grants this ability to them as well. It's a fine way of ensuring that the Squigs go where they're supposed to. Costly, maybe, but quite useful if Squigs are what you're going for.
