Disney Moana's Necklace Light Up Magical Seashell Heart of Te Fiti Brand Name: Disney Moana

can the batteries be replaced?

No where in this does it say it sing but a previous question said it did. just making sure this lights up and plays music.

How long is the necklace? how big is the pendant? how does the heart light up? is there a button we need to press? where is it?

Does the stone heart come out?
