Biome update (1.19)

Crabs, waves, tsunamis, sea urchins and palm trees (palm wood would be cool) for beaches. For volcanoes, erupting, dried lava and new blocks. For swamps, frogs, alligators, new swamp blocks, (maybe swamp wood) and lizards. For snow biome, penguins, icicles, and other blocks and mobs! I just think Minecraft has to have better biomes and new ones, also new structures would be cool :)
