Fan creation by TheKalais. Set 31025 Mountain Hut is a City themed set. Oh, you want to play with Castle and Monsters now? No problem! Check out how easy you can turn this set into a custom medieval/fantasy set! Note: 100% sounds made by me. I also designed the castle. Mountain Hut Goes Castle is one of the entries for the LEGO® Rebrick Creator Build and Rebuild contest.
