"Little Man", as I've named him, is currently exclusive to set 7789 Lotso's Dump Truck.
Minifigure Parts and Accessories
This figure is a bit of mystery. He hasn't official been listed as a minifigure that comes with the set, he just sits passively in the driver's seat of the dump truck. I feel he resembles the old-school, Fisher-Price Little People.
"Little Man" is composed of a yellow construction hat, minifigure head with eyes and nose, and a dark blue torso comprised of part 30151. The dark blue is a new color for this part.
Army Building Potential
I imagine the ABP for this figure is low. I don't see this figure being sought in multiples unless there's high demand for part 30151 in dark blue.
Its hard to tell at this point. We may have a new color for the domed part and the minifigure print on the face is new. The had appears to be a standard yellow version of part 3833. Are these big draws? Only time will tell...
