Island Interchange Biome
Terrain
Animals
Crab
Crabs will turn the water into sand that can be walked over, as well as reveal stones during the high tide. This allows you to be able to get to areas without bridges and to access stone if needed.
Threats
Cloud
The cloud will seek out the tallest item stacks on the ground and actively try to push them into the water. When an item stack is pushed into the water it is lost. If the player looks at the cloud it will move away from the player, but, if the player is not looking in the direction of the cloud, it will hunt for items to push into the water.
Boss Fight
Octoboss
The Island Interchange bossfight is the Octoboss. This boss appears in the ocean with a number of tentacles which fling water across the map. When a tentacle's projectile hits the map, it will permnently change that location into pure water. If the octoboss's tentacles are not all destroyed before the octoboss goes underwater, the map is all converted to ocean water, making the level extremely hard to traverse. However, if the tentacles are destroyed, the map is left in low-tide, allowing the players to move around the map more freely, and get access to stone.
It is recommended that players instantly get a tool and attack the octoboss's tentacles as soon as the low-tide appears. Not destroying the tentacles allows the octoboss to turn tiles into water, and create a high-tide which can starve the players of resources that might be needed to craft tracks in order to get to the end of the level.
