Large groups: The more, the merrier

Having a bunch of people at once, all nearby. Maybe all standing straight up, or all laying next to one other, or something similar. Limits should be in place to not out-do the rest of the game's content in terms of what can be done to them (maybe automated things only) and who can be there (only squirrels or rabbits or something, for sanity of coding / rendering). But ... would be entertaining in its own right, and maybe a late-game source, high-yield source of samples, and only available once your lab has progressed and become popular in the squirrel community or something. Would be a natural reward of progression. Certainly would lack as much of a personal touch, but maybe that's its own fetish.
