I love your mod, if you want add more texture and functional tails

I love your 'mermod' mod! If you'd like, for the next update or previous version , please add:

Sculk tail (Mermaid Sculk): transforms into a sculk for every block when you touch. If you stay still, it spreads more (inspired by Vichobal's datapack: https://www.planetminecraft.com/data-pack/lo-que-toco-se-vuelve-de-sculk/ ), and her swimming animation is inside the sculk block, other block relation sculk and water (burns fast if touch lava or fire)

Nether tail (Nether Mermaid): Can swim in lava, and her vision is clearer, less reddish. She doesn't get burned, and swims like water (touching normal water causes damage).

End tail (End Mermaid): Can swim through the air (contact with water causes hydrophobic damage).

I hope you like my idea, and I admire your effort, bro :)

Sculk tail (Mermaid sculk): When swimming inside a sculk, vision is clear for 8 blocks, like an "x-ray mod" you can see as well first, second and third person (you can only see any block when you touch it or remain still; sumerge or trhought the sculk block can see it). (some blocks cannot transform into sculk: gold block, coal mines, etc.)

If the player swims inside a sculk block (another block related to sculk) and removes the Sea Necklace, they suffer suffocation damage while inside the block.

Nether tail (Nether Mermaid): If the player is in contact with fire or swims in lava and removing the Sea Necklace, causes damage.

End tail (End Mermaid): If the player swims at a great height, removing the Sea Necklace causes fall damage (depending on the player's height).

That's all; I've expanded on th idea a bit. If you have other idea, you can add more or stay my idea...that's it, have a nice day :)
