Another mechanic that I coded for the first time

"Grab Canceling"

The only thing that varies between character is: how long will they actually throw the opponent while Pressing Y + Holding FWD/Pressing Z + Holding Backwards will still do the cancel trick

Act Music as Rounds? (may not apply to every stage)

Despite being Water (Or Mutated Chao) slime sounds

Yoshi and Birdo cosplaying as Ichigo Momomiya

That Hover Move.

It's like the OG game but less stiff.

2/3 of them are references to

Sonic's Concept and is also a Skin in Sonic Superstars Cream's Debut (Though inconsistent looks)

A former 90s rival's (A red capped plumber guy) recent 3D platformer since 2017

I'm taking you down like its 1998/1999!

The "Big Green Man" (Guest) teaser.

Continue. But classic

A returning move from Infinite Battle

but a bit more on Sonic 06's Green Gem.
