…Population Crash says “take a card from the draw pile and place it on the discard pile,” instead of “draw a card and place it on the discard pile.” If a Creeper comes up this way, does the active player have to take it and put it in play, or does it just go on the discard pile?

A: We would rule that this should be functionally treated like a Draw. Thematically, think of any Creeper/s drawn as causing the Population Crash.
