Yeah, another idea I just got.
For this one, you may use as many skills as you want, BUT you may only use one skill on each lemming.
I've already done Fun, and all of them except 4 and 26 are possible.
*I have added any level which showed up in my previous topic as being possible with either Climbers, Floaters, Bombers or Blockers to this list, as well as any from the Minimum Skills that can be done with 0 or 1 skills, as these ones are obviously possible under this challenge*
