What about in the comic and manga adaptations?

Toadsworth died of stroke.

Mario never invites Bowser to his parties because Bowser's too good at it. Seriously tho, every time Koops picks Bowser in SMP, he wins easily.

That dice block is too good for this game.

After getting injured and beaten up so much during the final boss battle in DK64, K. Rool had his tail removed after the events of the game due to his injuries, explaining his lack of a tail. By the time of his appearance in Super Smash Bros Ultimate, it had finally started to grow back as a small stubby tail, and time will tell if it will regain its original length.

Crocs don't regrow tails. Lizards do.

Bowser isn't evil at all and only plays the role of "villain" in the games. Outside the games, Mario and Bowser are great friends. This is kind of shown in the spin-off games though, so I guess it's not entirely a headcanon.

 

[Mcmadness]

I feel like you could just replace that with "none of anything in this series has actually happened, it's just a bunch of books, plays and films"

 

[YoshiFlutterJump]

I mean yeah, that does explain why there's a minimal continuity in Mario games (I know there is a Mario canon but it's very limited).

 

[Doc von Schmeltwick]

No there isn't XD
