Smash 3DS stage palette swaps

[haydyn]

I have been playing on a few stages on super smash bros 3ds lately and I have noticed that when you hold r whilst you are selecting a stage you can play the stage with a different color or a different layout (not the omega forms of stages) and iv'e found a few but if anyone has found anymore post them here.
so far I have seen these:
balloon fight - leaves turned orange
dream land - gameboy turned white instead of green
boxing ring - can switch between ssb version or the punch out!! version
nintendogs - (if you see the song "bath time" it has been done correctly and you will see cats instead of dogs

Wow I did not know this about the Game Boy stage, along with Balloon Fight (although I've ran into the orange version of the stage in Smash Run, I had no idea how that worked). Thanks!

EDIT: You meant L, not R.
