Squid Terrains are stages in Build A Boat For Treasure. Squid Terrains have Squid tails protruding out of the water, which flick and send boats into the air. Waves also come from the room's sides, which move the boat and damage it as well. This obstacle 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 got added back. It was the first obstacle to ever be removed. It's also the first obstacle to be restored.
