Can I turn into a mermaid when I touch water and have all 3powers?you should ask charlet to shut up

I don't know, but I personally don't believe in mermaids. Also, the things in H20 were made up, so if there are real Meerjungfrauen they might not be like they are in H20. They might not have the same kind of magic, oder any magic.

can I be a mermaid like you
