|Solid Triangular Foundation|
The Solid Triangular Foundation is one out of two foundation types available in the game, and is only visually different from the regular Triangular Foundation. Using the Solid Triangular Foundation, the player may build diagonal lines on the raft. If the Shark attacks a Solid Triangular Foundation, the player can destroy the foundation with an Axe and rebuild it instead of repairing it. Doing this uses no Material.
Building Solid Triangular Foundations does not count towards the Builder! achievements.
- Can be used to expand the Raft diagonally.
