- For the version in Plants vs. Zombies Online, see Oxygen Algae.
Oxygen Algae (氧气藻; pinyin: yǎngqì zǎo) was a plant and an environment modifier in Plants vs. Zombies: Journey to the West He was an aquatic plant, and as such can only be planted underwater. Since most plants cannot be planted underwater, the Oxygen Algae must be used. When planted, the player will be able to plant any other plant in a 3x3 area around him in Plants vs. Zombies: Journey to the West.
About
Oxygen Algae was the first plant obtained in the Fight the Sea Demons. He was integral to the waterlogged areas of Fight the Sea Demons and Brave the Dragon King's Palace as it provided oxygen in a 3x3 area around himself, allowing non-aquatic plants to survive underwater to fight various undersea zombies.
If eaten the surrounding plants would slowly take damage until either defeated or until another Oxygen Algae is planted in a nearby vicinity.
Origins

He is based on kelp, large brown algae seaweeds that make up the order Laminariales.
Oxygen Algae's abilities are a reference to real-life algae's ability to photosynthesize and produce oxygen.
