-Spoilers i guess-
For all of those who played Super Mario Galaxy 2, there was a Galaxy named "Boss Blitz Galaxy". It was a galaxy about beating 5 bosses from Super Mario Galaxy. If you haven't noticed yet, those were the best representative for that game. All of them involved no items. With that in mind, what do u think should best represent Super Mario Galaxy 2 if they made another game with a same type of theme as Boss Blitz.

List of Bosses:
Peewee Piranha
Giga Lakitu
Digga-Leg
Gobblegut
Rollodillo
Sorbetti
Megahammer
Glamdozer
Squizzard
Prince Pikante
Bowser Jr.'s Boomsday Machine
Fire Gobblegut
Giant Bowser
(note i did not include the five form Boss Blitz Galaxy, Whomp King, and Bugaboom)

megahammer, fire gobblrgut, pewee

peewee,gobblegut,sorbetti,squizzard(EPIC BIG MOUTH DUDE),and fire gobblegut

fire gobblegut, gobblegut, and digga legs

Peewee Piranha, Giga Lakitu, Glamdozer, Squizzard, and Fire Gobblegut should be the ones in the second version of this galaxy.

Gobblegut,Bowser,That Bowser Jr Robot,Bowser again,The Boomsday Machine, and Bowser again XD sound hard? It would be even more hard on DAREDEVIL or SPEED RUN
