We start the aftermath of Chapter 7 with Bowser. Peach, of course, has been taken away for Secret Reasons the game is having a lot of fun keeping from you, and telling you what she's doing would a) spoil the surprise and b) not be very fun.
Again, I wish we had Bowser comic relief after escaping the X-Naut Fortress, we just came off beating up Crump.
Surprisingly, if we were going in the pattern of Bowser always being two chapters behind, Poshley Sanctum is where he should be this time. I always assumed they had abandoned the "two chapters behind" thing by now and were just sending him to fake Crystal Stars.
Spoilers, Pennington had another one.
All we've gotta do is walk right up to Poshley Sanctum.
No reason not to terrorise the locals. And Kammy, too, who probably decided to take herself up on this suggestion and retire to Poshley after this game.
...The people of Poshley Heights seem surprisingly impervious to Bowser's presence.
...Toodles what the fuck
Toadia is more Bowser's speed. Although I don't think the Toads normally call for their parents when Bowser arrives.
