If you don't get the joke basically when you are playing the green Koopa Troopas will fall off the edge while the red Koopa Troopas will march back and forth and will never walk off an edge
my idea is something like that
basically Bowser is really hard on them and do sent give them a break
the red ones make fun of them for being useless bc there always being yelled at
This is why green koopas fall off LMAO
Red koopa: BRUH WHAT ARE YOU DOING
Green koopa: I'm walking on invisible blocks!
*Green koopa falls*
Green koopa: Oh, it wasn't invisible blocks...
Red koopa: Yeet...
