Incorporate waves into your little mermaid birthday party by adding a table skirt for a 3D effect.

Ariel, the Little Mermaid, is not just an ordinary mermaid. She is a princess! To make the birthday kid feel like royalty, string a banner for this royal occasion.

5. Under The Sea

Where does the Little Mermaid live? Under the sea of course! Twist and tape paper streamers to the wall and add fish cutouts in-between the “seaweed” to go for a “deep-sea dive.” You can also decorate with ocean theme decorations. Make sure that when you are buying decorations that they are either dark blue or baby blue (ocean colors).

Have guests bring their favorite picture showing a memory with the birthday kid, and display them on a wall. Hang decorative fishnet and use wooden clothespins to hold the pictures.

Besides her tail, Ariel is known for her melodious singing voice. Have a karaoke party for everyone to sing their favorite tunes.
