Since I changed Yoshi's palette to use palette E (A rotating palette), I accidentally stumbled onto something. When I ate a blue shell with him, I noticed that I couldn't fly and when I ate a yellow one, I could fly and make sand clouds. So i decided to see if changing Yoshi's palette number did anything else to the shell powers. Here are my findings:

---

Palette 8: (Basically a copy of the Blue Default)

G: Fly
R: Fly/Fire
B: Fly
Y: Fly/Sand

-------
Palette 9: (Basically a copy of the Yellow Default)

G: Sand
R: Sand/Fire
B: Sand/Fly
Y: Sand

-------
Palette A: (Yellow Default)

G: Sand
R: Sand/Fire
B: Sand/Fly
Y: Sand

-------
Palette B: (Blue Default)

G: Fly
R: Fly/Fire
B: Fly
Y: Fly/Sand

-------
Palette C: (Red Default)

G: Fire
R: Fire
B: Fire/Fly
Y: Fire/Sand

-------
Palette D: (Green Default)

G: Normal
R: Fire
B: Fly
Y: Sand

-------
Palette E: (Strange mix here. Blue shells do nothing.)

G: Normal
R: Fire
B: Normal
Y: Fly/Sand

-------
Palette F: (Strange mix again. Looks like an incomplete Yellow default. Note that blue and yellow are the same.)

G: Normal
R: Fire/Sand
B: Sand
Y: Sand

The last two palettes are really strange. At least I understand now how the special Yoshi's have their powers. I knew it had something to do with palettes but I couldn't figure it out before.
Now, since I'm planning on keeping Yoshi on palette E, I need to figure some way of either working around the blue/yellow shell changes or adapting them to fit. Now, I wonder if this same palette/shell power thing affects Koopas as well...
