Well, who knows when this adventure is taking place. Mabey Bowser has been cocky for so many plots that, he's starting to catch on...? =/
Haaaaaach, I see your point, but I still think Bowser would have no reason to kidnap Pokey's brothers if he just wants to tease Pokey, saying "Ha ha, you won't defeat my army!" or something. Letting Pokey test the strength of it is at least a bit reasonable in my opinion.
If anyone comes up with a better plot than mine (which shouldn't be that hard), feel free to let me know. ;)
Also, I worked on the level "Amapola Ghost House" today, and it's almost finished already! If I keep on working that fast, world 2 will be finished by next week or so. I'm quite confident either a demo or a trailer will be released at the next C3 - unless I take another long break, that is. :/
