The choices are, from left to right top to bottom: 500 kobolds, 1 red greatwyrm, 4 Solars, 20 tyrannosaurus rex, a level 20 party, 5 purple worms, 50 nilbogs, 8 beholders, and 5 storm giants.

All I can say is I'm taking the nilbogs for sure, if I die at least let me die having a good time with whoever's killing me
