Alright, done! It looks a lot better this time.
So yeah, you face back, after seeing that facing front shows you an unattractive giant wall upon loading :P
I really don't like those almost pure white textures, but hey, it showcases the parallels. The back showcases Sprinin' Around, Snow Mountain, and Egg Factory. Also, the wall on the left IS aligned horizontally, just not in this shot. I changed it after taking it.
This half showcases Green Christmas, Glimmering Cave RMXs (if that's what it's called, I can't remember), and Holiday Village (Kinda).
The holes have the exits in them (Note: the water is different on both sides).
And underwater red springs are in them too.

Just replace Map 01 with this.
