Mermaid Under-the-Sea 6th Birthday Arch

A dreamy under-the-sea mermaid 6th birthday setup with a round 'Happy Birthday' coral-reef backdrop, an organic balloon arch in pastel pink, purple, mint, peach & chrome-silver, a giant mermaid-tail foil balloon on top, mermaid & tail cut-out standees, a pink coral-printed cake pedestal, a marquee '6' light and scattered pastel balloons on the floor — recreated from the reference photo.
