Yeah, I'd like to see another spinoff too. Imo those are the best ones and the ones that are less likely to be yet another simultaneous clone of Kirby Super Star and Kirby 64.
I mean, don't get me wrong, those are awesome games. But many of the games since that era have just incorperated elements from those two over, and over, and over and over and over-
It was honestly pretty cool in Return to Dreamland, and working so similarly to RtDL worked well for Triple Deluxe, but after Robobot and possibly to an extent Star Allies doing the same thing as well (correct me if I'm wrong though, I've never played Star Allies other than a brief GameStop demo), I think it'd be nice to see something a little... different from the usual "team up with your helpers and find scattered crystal shards/energy spheres/sun stones/code cubes/etc., then fell your true enemy!" this time, instead of just expecting the same old thing.
Whatever it turns out to be, I hope Bandana Dee gets to continue the perfect attendance streak he's had since Mass Attack. It's gotten to a point where the games wouldn't feel right without him at least tossing items to Kirby from the background.
"Now then, hero of the Lower World...
You would risk your life for this land?
You would stand against me, the ruler of the
heavens? Very well... You will before the great
Queen Sectonia. My beauty rivals the divine...
and my power will crush all you hold dear!"
"Bah... Aha... I see. I expected as much from the
hero chosen by the Dreamstalk. But I wonder...
how will you handle this? You see, true beauty...
is control. The Dreamstalk has guided you thus
far. But its bloom... will be your doom!"
