Ok so, spoiler alert: y'all are about to completely obliterate the remaining bird monsters.
Which is fine... except for the fact that the reason why I sent them in your direction in the first place was so that the birds would then try to escape by flying back in the opposite direction, and then your group would follow them, and have a reason to join up with the other characters who are falling down Undertale's hole.
And you don't have to go along with that plan if you don't want to... but, that was my attempt at making sure your group doesn't just fall into a sort of "ok, what now?" state where no one has anything to do. And if the bird monsters are all defeated, then... I feel like the group would just sort of be like "ok, what now?" and have nothing to do.
So if you guys have any other suggestions on where to go from here, and what can be done to make sure your group has something to do... do let me know. Because I don't want to just make an IC post that basically just says "lol, they ded" and then leave you guys to stagnate after that.
