I just want Bonfire to be much bigger, right now everyone's praticly all crampd up into one small space.
Though, I wouldn't mind there be a waterfall coming off from the top of the island- where the on stone is perched that comes down into a sort of miniature lake that leads off into the water.
The Adoption Center isn't anything 'official' though, just something a sort of kind user decided to put together, I don't think that really deserves it's own private cave, and either way people would probaly just roleplay in it or something of the sort.
As for the Dancefloor idea, simply too unrealistic, I believe Kovu wants FeralHeart to be as realisitic as possibly.
For the Beavers, Monsters, Fish, etc... those aren't exactly 'official' things either, there just among the few things that people create just so they can, well I dunno really.
