Sponge Fortress

The Sponge Fortress is a generated structure found in the Spongeland Dimension.

Structure
Sponge Fortresses look like small castles, and are made entirely out of Sponge blocks, other than the wooden fences surrounding the top floor. Inside the fortress, there are four sets of ladders (all leading to the top floor) and occasionally a Venturechest.

Venturechest
Each time the player enters Spongeland, there is a chance that they will find a Venturechest (or two) inside the Sponge Fortress, at either the top or bottom floor. On rare occasions, there will be a Venturechest on both floors. These chests randomly contain a sword, food, or even armor. However, if the player leaves Spongeland, only food can be carried to the next dimension.
