Gender reveal ideas

If I have a boy I want the nursey to be done in lion king (mostly simba) and if it's a girl it will be the little mermaid. So for my gender reveal party I'm thinking that the person who know the gender ( we won't until the party) will play either under the sea or a lion king song and the theme for the party can be either lion king or little mermaid. So cute, what do you think?
