I didn't design the trapdoor logo that can be found here along with the characters.  https://makerworld.com/en/models/1485652-the-trap-door-1986-characters-and-logo?from=search#profileId-1552145

I did though design the dungeon.  I would suggest scaling the figurines down to fit within this scene as berk is a giant in this dungeon.  If you use the figures on the link above.  I actually left the tree supports on on purpose as i felt they kinda add to the age of the dungeon.
