The Geyser Terrain is a terrain in Build A Boat For Treasure. It has geysers, hence the name. Upon a boat touching a geyser, it will fire a stream into the boat, launching it. Occasionally, it could launch a boat out of the terrain and into the void, however, an invisible ceiling has been added to prevent boats from flying out.
The Geyser Terrain contains 8 waterfalls in total, 4 on each side. Players can go inside of the large waterfalls on the right and they can gain access to a potion room that requires a puzzle to unlock Chillz' Plushie.
