The Squid Terrain is a terrain in Build A Boat For Treasure. Squid Terrains have tentacles protruding out of the water, which scream and flick the boat on contact, sending it into the air. Waves also come from the room's sides, which move the boat and damage it as well. This terrain was removed, and was possibly due to it glitching the boat so it stays put. It was removed sometime in 2018 mostly due to the glitches it had caused. Afterwards, on 8/8/2018, it was added back. It was the first terrain to ever be removed. It is also the first terrain to be restored.
