No, whats cool are these two have been classic nemisess of Mario, and now they finally take each other one. But why is Mario's biggest enemy, taking on Mario's oldest enemy? If anything, shouldn't they be teaming up? Or maybe since DK stopped with the bad guy gig, Bowser is trying to coax him back into it by stealing his bananna's?
Bowser: Help me kill Mario again and I'll give you back your Banannas!
Donkey Kong: OOOOHHH! BA-NA-NAAA!
Diddy Kong: ...
Not really sure what Diddy will do, or if Bowser even planned for Diddy to be there, or hell, if Bowser even knew Diddy existed. This is the first time they actually meet after all (not counting non-story games like Mario Kart).
