I never understood why they decided on that name for the game. I mean, up until then, most Kirby games took place in Dreamland anyway, so what's he returning from, exactly?????
Anyway, sometimes I think about who player 4 could've been in that game if they didn't upgrade BWD. As far I can tell, the only other playables around then besides Meta Knight and D3 were helpers from Super Star, Gooey, and the Animal Friends (to a lesser extent, the Waddle Dee from K64 too). I imagine Gooey would've been the choice, and he would be similar to what he it is Star Allies instead of a secondary Kirby playstyle. Heck, I could be speculating for nothing, as player for could've just been Keeby, considering the alternate choices.
