Fight the Sea Demons (力战群海妖; pinyin; Lìzhàn qún hǎi yāo) (also known as Underwater World) was an area in Plants vs. Zombies: Endless Edition and is the sixth area exclusive to the former's Adventure Mode. This area took place in an underwater palace, presumably in the East Sea.
This area was completely water-logged with sun falling in a serpentine pattern rather than directly down, and plants requiring the aid of Oxygen Algae to remain planted. When not in the vicinity of an Oxygen Algae, plants will slowly drown and take damage until either defeated or when an Oxygen Algae is planted nearby. It also is one of the only 2 areas from journey to the west to not appear in Great Wall Edition.
Many plants are also unusable underwater, including:
- All Mushrooms except Magnet-shroom
- Lily Pad
- Tangle Kelp
- Sea-shroom
- Cattail
- Grave Buster
- Torchwood
- Flower Pot
- Coffee Bean
