Hi Mojang, we have a sound issue with Seagrass, it doesn't have a special sound when broken by the player like in Java Edition. It instead plays the same sound as a plant breaking.

STEPS TO REPRODUCE

Find or place down Seagrass (it has to be underwater)

Now break it

Observe how it uses the plant breaking sound instead of a unique one.

       Here is a link where you can find the sounds on Java and Bedrock Edition. https://minecraft.fandom.com/wiki/Seagrass?so=search
