I thought of a cool new category where you have to get the stars from the game's bosses not counting the 3 Bowsers (which you fight anyway) glitches are allowed, so you can finish the game after beating all the bosses.

Rules: You must obtain these ten stars

BoBomb at the Summit
(BoBomb Battlefield)

Chip of Whomp's Block
(Whomp's Fortrace)

Going on a ghost hunt
Ride Big Boo's carousel
Big Boo's Balcony
(Big Boo's Haunt)

Stand Tall on the Four Pillars
(Shifting Sand Land)

Boil the Big Bully
Bully the Bullies
(Lethal Lava Land)

Chill With the Bully
(Snowman's Land)

Make Wiggler Squirm
(Tiny Huge Island)

Then beat the game. You may have to Collect additional stars to unlock certain levels, making the category all the more interesting. That's my suggestion.

This category kind of already exists in the MST CE although it excludes Big Bullies and Big Boos. There is also another potential CE, All Enemies, that kills all the Bosses. But that doesn't mean this couldn't be a CE on it's own.

You may also want to include the Big Eye in BBH.

Fun fact, according to Ukikipedia, the Manta Ray in DDD is considered a Boss: https://ukikipedia.net/wiki/Manta_Ray

You're right about the eye in BBH I realized I missed him. I didn't really think of the manta ray either.

Looks like there is already some interest: https://docs.google.com/document/d/1pDP4efbBaeXGUpcLopV9fP1xVWWyjTa-slWLjwvy-vA/edit

I didn't know that stingrays are classified as boss in DDD for the first time So BBH has a boss in eyes and JRB doesn't have a boss?

Does Unagi in JRB count as a boss?

If you really wanted to get crazy you could make "boss" include all stars held by NPCs where interaction with the NPC is required to get the star. Would add both Koopa races, Lil Penguin Lost, CCM slide race, Can Eel Come Out to Play, Manta, THI Piranha Plants, monkey cage, and maybe some more I'm missing.

I think all bosses should just be bosses that have music, since Nintendo intended to make a difference between wiggler and big boo for example
