Oh wait, the point I was missing there is that you are supposed to always move BOTH dingoes, not just one. I re-read the rules for the third time or so and only now realized that they clearly state that
It wasn't at all clear to me. The way I interpreted it was "first roll the die to determine which dingo moves, then roll it again to determine how far it moves."
And it took us close to 20 minutes to figure out that the last player controls the dingo. That was in setup but it should've been in the dingo section as well.
