I have been working for quite a while on Ooo, which is the setting for the television show "Adventure Time". I thought it would be awesome to make the whole map so I made it around 3000x3000 blocks for the size of it to fit in all the castles and locations of the show.

I started by making Finn and Jake's Treehouse and the Ice Kingdom and once I finish that, I will start on the Candy Kingdom and put a download for what I have done so far.

I have also added a .schematic for Finn and Jake's Treehouse as that is probably something people would want for their maps. The interior isn't completely finished for it as there are a couple empty rooms.

I also included a picture using leonel's "Adventure Time Craft" texture pack. I highly recommend downloading it for any level! I plan on making the whole project compatible with his/her or anyone else's Adventure Time texture packs.
