Mangrove Swamp is a new biome inspired by what is known in real life as a mangrove. In this case it is a swamp biome where we will find a new animal and a new type of tree. Although it may seem like a slightly lazy update in terms of content and news, it is worth remembering that we come from two updates where a lot of new content has been added. Minecraft 1.16 was the Nether update and later Minecraft 1.17 which, due to the pandemic and remote work had to be split into two parts, focused on something as transcendental as the generation of terrain and the maximum height of the world.
