post any random Mario thought on your mind

If by progressive you mean non-existent.
 
*M&L Partners in Time introduces Baby Peach*

Yoshi's Island DS expands on more baby characters, adding Baby Peach, as well as Baby Wario and DK to the Yoshi series.

*then there is Baby Daisy in MKW*

Yoshi's New Island tries to feature just Baby Mario and Baby Luigi.

*MK8...Baby Rosalina exists*

Yoshi: "That's it! I'm done with babies. Moving on to wool and crafting."
 
The only baby characters worth a crap you can count on 4 fingers.
 
I consider it a blunder that they don't have a yarn Baby Mario or Baby Luigi.

though craft world isn't that much of a loss. i don't want Baby Luigi to appear as a moldy cheetos.

hell, i can just go crazy with the terrible fuzz effect myself. not that i want to.
 
I'm kinda glad they aren't in them myself. Yoshi's Island had all I wanted to see of the babies with yoshi and that's primarily due to how the game ended. Any appearance after that (again with yoshi) just cheapens it.

I'd prefer they stick to spin offs where they can shine more on their own. Sports, karts, rpgs, parties, whatever.
 
C'mon a Yarn Baby Luigi would be irresistable
 
I'd sooner take a mystery dungeon game starring the babies.
 
that works too!

chocobo has a mystery dungeon, it would work splendidly on the babies
 
I feel like I wrote a basic premise for it in a topic like, 4 years ago.
