 Spoiler

:f6:

also, some speculation...

 Spoiler

1. A Statue of Mushroom Liberty. a 4th dungeon?

2. the MapleStory sign. why can't there be something hidden there?

3. the supposed Vineland/ Krakia area. note that the trees change.

4. rainforest south of the city. space for the Yetinx, or the road for the badlands?

5. that Southeastern patch of land in the clouds. Vic, Amoria, or Masteria?
